TS4-TWS-049TEMPERATURE SENSOR

Tehama Wireless Design Group 11/14/2005 1 of 3 TempSens User Guide General Description The TempSens system consists of three device types to remotely monitor temperature readings and provide the data to a PC for formal presentation and reporting. Sensor devices will be placed in all locations requiring local monitoring of temperature. The Sensors will transmit time stamped temperature data to the single Base device in the system, which receives the data and forwards it to the host PC via a USB interface. For sensors that are out of range from the base, Repeater devices can be added in appropriate locations to relay the data between sensors and the base. The system will operate in the 865MHz (Europe/Asia) and 915Mhz (US) ISM bands using off the shelf FSK RFIC radios. The system will operate over 60 narrow band frequency channels with a baud rate of 4800bps, incorporating a bidirectional communication link with Acknowledge (ACK) messages to ensure all data reaches the base. The sensors are battery operated, bursting data packets at pre-programmed times then shutting down to conserve battery life, estimated to exceed 2 years. The repeaters will be line powered, while the base unit will be powered via line or USB interface used to communicate with the PC. With an average sensor transmission rate of four per hour, a single Base can accommodate many sensors. Through the use the ACK messages and local memory in both the sensors and repeaters (to store transmitted data that has not been confirmed as received by the base via an ACK message), the number of sensors supported can approach the theoretical maximum. There is no limit to the number of repeaters, though an average installation may require 1 repeater for every 10-15 sensors.

This utility can be run on the PC either prior to or during a site installation, or when new sensors are added to a system. All sensors come from the factory with a default configuration, and the utility need not be run if no sensors are required to deviate from the default. The Utility will allow the following options to be configured on a sensor: • Transmit Interval, defined as the time between scheduled transmissions of temperature data. A temperature measurement is taken every Transmit Interval, and the data transmitted within 60 seconds after the measurement. The units for this parameter are seconds, and the default value is 900 seconds (15 minutes). • Measure Interval, defined as the time between scheduled temperature measurements. This is used in conjunction with Temperature Change (see below) and must be smaller than the Transmit Interval time. A value of 0 for this parameter will disable measurements in between the Transmit Interval. The units for this parameter are in seconds, with default set to 0. • Temperature Change, defined as a percentage change in the Thermistor resistance value (i.e. temperature) detected by the sensor. A Delta Temp alarm will be generated within the PC Software if a Sensor reading taken at a Measure Interval is more than Temperature Change percent from the prior Transmit Interval value. The units for this parameter are Percent (%), with the default value set to 0. No other parameters are configurable on the sensors. Absolutely no parameters are configurable on the Base or Receiver. NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT Tehama Wireless Design Group 11/14/2005 3 of 3 Usage With the Configuration Utility running on the PC, the user will install batteries into the sensor to be configured and set the Power jumper (orange). This will cause the sensor to communicate to the base and provide the currently configured parameters along with the Sensor’s unique ID number. This information will be displayed in the Config Sensor tab of the Utility. The user should change the parameters as necessary, then hit the Set button to send the changes to the Sensor. The Sensor will receive the new data and store that data in non-volatile memory. Once a sensor has been configured, it will begin to operate normally, trying to send data as programmed and sleeping otherwise, however the PC software will not receive any data from the sensors until the Configuration Utility is closed. If the configuration is being performed away from the installation site, the battery or the orange jumper may be removed for shipment, as the new settings are stored permanently in the unit. Sensor Placement With the Base Unit plugged into the PC and the PC Software running, the Sensor placement phase begins. All the Sensors should be placed at the necessary locations, then the PC program should be checked to verify which Sensors are within range of the Base Unit. Alternatively an Installation monitor may be used that pings the base and all repeaters, providing audible and visual feedback of the signal strength. With this and/or a rough drawn map of each sensor’s location, the need for repeater placement is easily identified. After the repeater(s) have been installed, the user will again check the PC program to see an updated list unseen sensors. If th…

Tehama Wireless Design Group 11/7/2005 1 of 2 TW-049-S Sensor Operational Description The TWS-049 unit is a 902-298MHz frequency hopping transceiver consisting of the main micro board PCB and a low power radio module PCB. Features/Specs • The TWS-049 functions as a Remote Wireless Sensor, recording sensor data and wirelessly forwarding the data to the companion TWB-049 Base/Repeater units. • The system supports over 500 sensors with 15 minute transmission intervals. • An internal thermistor type sensor or external sensors are supported. • Powered by 2 AA batteries. • Battery life approximately 2 years with 15 minute measurement interval. • Jumper P2 acts as power switch (off w/o jumper) • The TWS-049 utilizes a Chipcon CC1020 RFIC (radio frequency integrated circuit) with maximum power output of +5dBm • Baud Rate = 4800 bps, Modulation is FSK with a 4.9kHz deviation • 60 channel frequency hopping system, minimum 400KHz channel separation • Dwell time per channel is 120mS maximum, 72mS typical • The TWS-049 is controlled via an 8 bit Atmel AVR micro (ATMega168V), clocked by its internal 8MHz LC oscillator. • The ATMega168V contains Flash ROM for program code, EEPROM for configuration/serial number, and SRAM for CPU operation, all internal to the IC • Real time clock maintained by 32.768KHz crystal Operation • The TWS-049 is configured by the user to measure attached sensors periodically with an interval time between 60 seconds and 18 hours. • At measurement intervals, sensor readings are taken by the micro and a data packet generated and queued up for transmission. The transmission time (and thereby channel selection) is chosen by a randomize function (seeded by the unit’s unique Serial ID) and a timer set to schedule the radio transmission. • At transmission time, receiver is first enabled to check for carrier detect (in case of interfering system or anther sensor). If carrier detect is clear, transmission proceeds. If another carrier is detected, transmission is delayed by approximately 100mS and the process repeated. If a carrier is detected the 2 nd time, the data is stored and the transmission rescheduled. • Upon transmission of data packet, the unit switches to receive mode to await the Acknowledge (ACK) packet from the Base/Repeater. If no ACK is seen, the data is stored in non-volatile memory for later transmission. • The TWS-049 can generate only one transmission per channel. • Typical configuration generates one transmission every 15 minutes • All transmitted packets incorporate a header that contains unique serial number ID of the transmitting unit. • The real time clock is synchronized via the acknowledge packet (ACK) from Base/Repeater.
