The micro-power wireless module uses LoRa modulation technology to transmit and receive data wirelessly. It is a wireless remote transmission module with small size, ultra-low power consumption, strong performance, and ultra-long transmission distance. The characteristics of high anti-interference and high reliability greatly surpass the traditional GFSK debugging module in terms of stability, anti-interference ability and receiving sensitivity.
LoRa wireless module function
LoRa wireless module function
Wake up wirelessly
It can realize remote wireless wake-up and respond to the upper computer processing instructions in real time;
Sampling
Can realize a variety of sampling methods, such as pulse, photoelectric, ultrasonic, etc., with high measurement accuracy;
Attack shut-off
It has the function of preventing external electric and magnetic attacks. When the sample is attacked by external electric or magnetic, the meter can automatically close the valve and alarm;
Remote control valve
With remote valve control function, the valve can be opened and closed in real time or combined with pre-paid and post-paid to realize automatic remote on-off valve function;
In place detection
With switch in-position detection function, when the normally open contact is closed in place, the valve switch is in place, and the valve operation can be stopped immediately;
Trigger / button upload
The module is always in an ultra-low power consumption state, and the module can upload real-time data and working status by magnetic trigger or button;
Low electric shut-off valve
When the battery voltage is lower than a certain value, the module can automatically close the valve and upload data once;
Shut-off valve
Used in conjunction with a fara capacitor, the meter will automatically close the valve when the meter is powered off to prevent accidental or man-made power outages from being metered. After the power is turned back on, the meter will return to the state before the power failure;
Valve failure detection
Automatically determine whether the valve limit switch is working normally. At the same time, even if the limit switch fails, the valve can still be opened and closed normally. When the valve status is abnormal, an alarm will be displayed in the background;
Reed switch failure detection
When a sampling reed switch fails, the meter will upload a reed switch fault prompt, and the meter can still accurately measure.
