An Ying high accuracy soil humidity sensor, intelligent soil moisture meter 0~5V/0~2V output for farm, greenhouse.
Function Instruction:
A-SM1 is a high sensitivity and precision sensor to detect the real time moisture of soil directly and stably through dielectric constant. A-SM1 adopts International Standard measuring method to measure the water content of soil. It can be used in Soil Moisture Measurement, Scientific Experiment, Water-Saving Irrigation, Greenhouse, Flower & Vegetable, Grass & Farm, Soil Quick Testing, Plant, Sewage Treatment, Grain Storge, Precision Agriculture etc, and also in Water Resources, Weather, the water content measuring of particulate matter and so on.

Competitive Advantage:
- High sensitivity and accuracy, good interchangeability.
- Reliably sealing, corrosion resisting, long service life in the soil.
- With flame-retardant epoxy resins to make sure strong waterproof and anti-impact of external forces.
- Made of high quality steel, the sensor can endure long time electrolysis and the corrosion of acid & base in the soil.
- Protected from inverse wire connection.

Connection
- Red(V+): Power(V+)
- Black(G): Power (GND)
- Blue(O1): Signal output (temperature)
- Brown(O2): signal output (water content)
- Yellow: No connection
- White: No connection
- Green: No connection
RS485 Mod bus communication protocol
- Red(V+): Power (V+)
- Black(G): Power (G)
- Blue(O1): No connection
- Brown(O2): No connection
- Yellow (T+): RS485+/A/T+
- White(T-): RS485-/B/T-
- Green(SET): when connect to “ V+”, it will start in “ setting ”; No connecting or connected to “ G ”, it’ll start in “ Operating ”
The configuration parameter of the module like Modus address, baud rate, check digit, communication protocol etc is saved by EEPROM (power storage device )inner. Due to absence from the specific configuration of the module, it can transfer the communication to the modules sometimes. To solve this problem, there’s special mode of the module called “ setting mode”. When it starts with “ Setting mode”, it’ll communicates as following parameter:
- Modbus address is 0.
- Communication configuration is 9600,N,8,1(9600bps, no check digit,8 data bits, 1 stop bit).
- Communication Modbus-RTU The configuration parameter of EEPROM will not change because “setting mode” or “ operation mode” starts.
