Overview The Pulse Reader (ID: WRW-E1) integrates hall metering, acquisition, communication and transmission. It can be able to monitor abnormal conditions such as magnetic interference, low voltage of battery and disassembly in real time, and actively report it to the management platform. The pulse reader and the gateway form a star network, which is convenient for network maintenance, with high reliability and strong scalability. It complies with LoRaWAN1.0.2 standard protocol. 2. Metering Module Feature 2.1. Electrical characteristics No. Feature Function Description 1 Working frequency It’s compatible with LoRaWAN®,EU868,AU915 are optional 2 Maximum transmitting power It’s in accordance with the requirements of power limit in different areas of the LoRaWAN protocol 3 Working temperature -20°C ～ +55°C 4 Working voltage +3.2V ～ +3.8V 5 Transmitting distance ＞ 10km 6 Lifespan ＞ 8 years （ use one ER18505 lithium battery ） 7 Waterproof degree IP68 2.2. Feature Description No. Feature Function Description 1 Data reporting There are two data reporting methods. Touch to report data: touch the button twice, touch the LED light to light up, lift up the LED light to go out. It must be greater than 2S at the first touch, it must be completed within 5S at the second touch after the first touch and it’s less than 2S, otherwise it’s invalid. Actively reporting at regular time: The period and time of timing reporting can be set. The value range of the timing reporting period is 600~86400S, and the value range of the timing reporting time is 0~23H. After setting, the reporting time is calculated according to the DeviceEui of the metering module, the regular reporting period, and the scheduled reporting time. The default value of the regular reporting period is 28800S, and the default value of the scheduled reporting time is 6H. 2 Measurement Support 10L/P single hall 3 Power-down storage Support power-down storage function,there is no need to re-initialize the measurement value after power-off WRW-E1 pulse reader P3 4 Magnetic attack detection It detects every 2S. When a malicious magnetic attack is detected, an alarm flag of magnetic attack and a historical magnetic attack will be generated immediately. If there is no magnetic attack detected for continuous 10 seconds, the alarm flag will be automatically cleared. The historical magnetic attack alarm flag must be successfully reported to the cloud platform before it can be automatically cleared. Neither the detected nor the cleared magnetic attack alarm will actively report data. 5 Low voltage alarm When the battery voltage is lower than 3.2V and the duration is longer than 30S, a low-voltage alarm flag will be generated; when the battery voltage is greater than 3.4V and the duration is greater than 60S, the low-voltage alarm will be cleared; the battery voltage 3.2V to 3.4V will not handle the low-voltage alarm flag. Neither detection of low-voltage alarm nor clearing of low-voltage alarm will actively report data. The accuracy of voltage detection is less than 0.1V. 6 Disassembly alarm It detects every 2s,when it detects maliciously disassemble,it will …

FCC 47CFR §2.1091 REQUIREMENT 2.1 TEST STANDARDS Follow the maximum permissible exposure (MPE) limits specified in 447498 D04 Interim General Radio Frequency Exposure Guidelines v01. The gain of the antenna used in the product was extracted from the supplied antenna data sheet and the maximum total power input to the antenna was also measured. Calculate the distance from the product to the MPE limit by the formula. 2.2 LIMIT For single RF sources (i.e., any single fixed RF source, mobile device, or portable device, as defined in paragraph (b)(2) of this section): A single RF source is exempt if: (A) The available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption may not be used in conjunction with other exemption criteria other than those in paragraph (b)(3)(ii)(A) of Part 1.1307. Medical implant devices may only use this exemption and that in paragraph (b)(3)(ii)(A); (B) Or the available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold Pth (mW) described in the following formula. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). Pth is given by: Page 7 of 9 Report No.: STS2302125H02 (C) Or using below table and the minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. For the exemption in Table 1 to apply, R must be at least λ/2π, where λ is the free-space operating wavelength in meters. If the ERP of a single RF source is not easily obtained, then the available maximum time-averaged power may be used in lieu of ERP if the physical dimensions of the radiating structure(s) do not exceed the electrical length of λ/4 or if the antenna gain is less than that of a half-wave dipole (1.64 linear value).
