Wireless remote water meter
Overview
The wireless module uses LoRa modulation technology to send and receive data wirelessly. It is a wireless remote transmission module with small size, low power consumption, strong performance and long transmission distance. The module's radio frequency chip is based on spread spectrum technology and has the characteristics of anti-interference and high reliability; it surpasses the existing GFSK modulation module in stability, anti-interference ability and receiving sensitivity.
characteristic
1. Using intermittent pulse and photoelectric sensor.
2. WOR electromagnetic wave wake-up technology, instantly wake up the water meter to make it in the communication state, and automatically restore the low power consumption state after the meter reading is completed.
3. Reasonable TDMA backoff algorithm to reduce the chance of data collision.
4. Adopt the latest nano-coating technology, no leakage electrode, and good sealing performance to ensure stable operation of the circuit board in a humid environment.
5. The construction is simple, and the complicated wiring construction problem is solved.
