M5ZTHLWireless Temperature/Humidity Sensor

FCC ID: M5ZTHL Installation and Operation Instructions for the Wireless Temp/Humidity. Point Six, Inc. Wireless Temperature/Relative-Humidity Sensor Model Point Sensor Temp/Humidity Installation and Operation Instructions The Point Sensor Temp/Humidity sensor transmits a digital temperature, relative- humidity (or light level) and a unique serial number to a 418 MHz receiver. The Point Sensor Temp/Humidity is enclosed in a high impact ABS enclosure for direct surface mounting in the environment to be measured. The Point Sensor Temp/Humidity is battery operated. Application: Apply the sensor to the surface to be monitored with double-sided adhesive tape. Make sure that the side labeled with FCC ID is visible and away from any metal surfaces. Service Function: The wireless sensor has an installation mode switch. A momentary push of this switch will start the convert/transmit cycles. When new and until this button is pushed the Point Sensor Temp/Humidity will not transmit. The Point Sensor Temp/Humidity will transmit a special installation status mark in the data packet immediately after the installation/start switch is pushed. After the start a push of the installation switch will result in the immediate transmission of temperature, relative- humidity ID and installation status mark. Battery: A 3.6 Volt lithium battery powers the Point Sensor Temp/Humidity wireless sensor. The battery will last for more than 10 years in the idle state (as shipped from the manufacturer). The Point Sensor Temp/Humidity will transmit data for as long as 5 years at a rate of once each minute once started. The Point Sensor Temp/Humidity is completely covered with a water resistant conformal coating to protect the electronics from the environment and condensation. The user can replace the battery. The Point Sensor Temp/Humidity may be placed in a quiescent state (battery life greater than 10 years) by holding the installation switch closed for more than 4 seconds. FCC ID: M5ZTHL Wireless Sensor Data Format The Point Six, Inc. 418 MHz wireless sensors require a compatible receiver with the ability to receive, error check and provide RS232 and RS422/485 interface. This document describes the data format provided by the HA8-wow 418 MHz. Receiver. The transmit packet from a receiver is approximately 15 milliseconds in duration and consists of 13 bytes of data: 1-byte ID/Mode field 8-byte serial number 2-byte temperature/relative-humidity or temperature/light level 2-byte CRC-16 error check The HA8-wow receiver processes this packet. The receiver performs a CRC-16 error check on the packet. If the data is not accurate it is discarded. When a packet is received that is error free it is converted to a 29-character packet and transmitted out the serial port at 19,200 Baud. The data is transmitted serially in ASCII Hex format and terminated with a CR character. This format requires two bytes for each byte of data; 14 data bytes x 2=28 plus the CR is 29 characters. See the HA8-wow specification for details. The resulting binary data format of the packet is: 1-byte ID field this field will contain a byte whose LSBit indicates the service state of the transmitter, 0=normal, 1=service mode. 8-byte serial# this field contains the serial number of the 1-Wire sensor. 2-byte data this field contains the temperature %RH stored MSB first. The MSbit of the MSB is the sign bit for the temperature value which is stored as the LSB in ½ deg C units. THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES, OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESERED OPERATION FCC ID: M5ZTHL MADE IN USA FCC ID: M5ZTHL Bits 0-6 of the MSB contain the RH value in %RH (0-100%). In the case of light level bits 0-6 of the MSB is the relative light level. 2-byte CRC-16 this is the originally received data packet CRC as described above. 1-byte checksum the checksum is a mod 256 sum of all the ASCII character values in the response but does not include the CR Example: C8 28AE9105000000AA2D2DD474AB<CR> This field is the mode indicator, the LS-bit which indicates the service state of the transmitter, C8=normal, C7=service mode. C828AE9105000000AA 2D2DD474AB <CR> This field is the unique serial number of the 1-Wire sensor. C828AE9105000000AA2D2D D474AB <CR> This is the temperature and %RH field. The MSBit of the MSByte is low so the temperature is a positive number, 2D is 45 so the temperature is +22.5 C. The %RH is 45. A value on this field of A1F2 would represent a temperature of (242-256)/2 or -7 C and a %RH or 33. Temperature is stored in the LSByte, if the MSBit of the MSB is 1 than the temperature is negative and the conversion math is (n-256)/2 otherwise use n/2. C828AE9105000000AA2D2DD474 AB <CR> This field is the CRC-16 error check as was originally received and checked. This CRC is over the first 11 bytes of the packet starting with the mode flags and ending with inclusion of the temperature data. C828AE9105000000AA2D2DD474AB <CR> This field is the mod 256 sum of all the ASCII character values in the response but does not include the <CR>. C828AE9105000000AA2D2DD474AB <CR> This is the CR terminator, 0Dhex.

FCC ID: M5ZTHL Operational description of the Wireless Sensor, Model Point Sensor Temp/Humidity Description of the circuit functions, ground system and antenna of the Point Six Point Sensor Temp/Humidity Wireless transmitter: The Point Sensor Temp/Humidity wireless temperature-relative humidity sensor is a lithium battery operated, microprocessor based, 418 MHz. transmitter that transmits both digital temperature data, a unique 64-bit serial number and either % Relative humidity or light level data. The microprocessor is brought up from a power down state every 4 seconds by a DS2417 time of day clock interrupt output. Relative humidity and light data are taken from a 12-bit ADC. The temperature is measured with a DS18B20 digital temperature sensor, which has a unique 64-bit serial number that can be read by the microprocessor. The microprocessor counts the 4-second interrupt cycles from the DS2417 clock until the transmit period has expired. The microprocessor then reads the temperature from the previous temperature conversion, combines it with the serial number and % RH or light level data and transmits the entire data packet serially with a Linx Technologies TXM-418-LC-R 418 MHz. Transmitter module. The microprocessor then starts another temperature conversion cycle and powers down into a quiescent state to wait for the next interrupt from the DS2417 clock. The PC board bottom layer is a ground plane and the antenna is a 1/4-wave loop that has been etched in PC board material and placed into the ABS enclosures cover. The entire electronics is coated with conformal coating to protect it from condensation.

Test Results: Tables 1, 2, and 3, and the Transmitted Bandwidth measurements show that this unit meets the radiated interference requirements of FCC Part 15, for an intentional radiator licensed to operate at 418MHz under Section 15.231(e). For the fundamental, under Section 15.231(e), the average limit is calculated by linear interpolation from 1500uV/m at 260MHz, to 5000uV/m at 470MHz when measured at 3m. Average limit = ((5000uV/m-1500uV/m)*(418MHz-260MHz)/(470MHz-260MHz))+1500uV/m = 4133uV/m = 20*log(4133) dB(uV/m) = 72.33dB(uV/m). Section 15.35(b) sets the peak limit for the fundamental to 20 dB above the average limit, or 92.33dB(uV/m). For spurious emissions, Section 15.231(e) sets the average limit to 20dB below the maximum permitted fundamental level, or 52.33dB(uV/m). Section 15.231(b)(2) permits this same limit of 52.33dB(uV/m) to be used for quasipeak measurements. Section 15.35(b) sets the peak limit to 20dB above the average limit, or 72.33dB(uV/m). Section 15.209 permits 53.98dB(uV/m) quasipeak from 960-1000MHz, 53.98dB(uV/m) average above 1000MHz, and with Section 15.35(b), 73.98dB(uV/m) peak above 1000MHz when measured at 3m.

To Whom It May Concern: The Point Six, Inc. wireless Temperature/Humidity transmitter (model Point Sensor Temp/Humidity) transmits a 15-16 millisecond packet once each 600-10 seconds. This is identical to the data packet timing of a previously certified “M5ZWOW”. The packet consists of transmitter-on/transmitter-off timing that represents the serial number and vibration data. The duty cycle is approximately 50%. The packet time can vary with serial number between 14- 16 milliseconds. The packet data is controlled by a microprocessor whose timing is based on a ceramic resonator that is very stable. The packet below (figure #2) illustrates a typical data packet, the worst case, 16 milliseconds, cannot be shown because serial number would have to be forced to make this so. Figure #1 illustrates the overall timing; a packet is sent each 10 seconds in this worst case. The battery used during the tests was new and was a standard 3.6 Volt Lithium cell. The battery is a 3.6 Volt Lithium chemistry, which has a flat discharge curve from new to about 90% used. In this application the battery requires about 5 years to discharge to the point that it cannot be used. The battery was used for no other purpose and had operated in the test unit for only a short time when the test was performed.
