Lietaus jutiklis modulis su LM393

Sensor and amplifier for rain or snow detection. Dual mode with analog and digital output. The digital output is used to determine the switching at, analog to measure the specific value of soil moisture.


Technical parameters:

- used comparator: LM393
- 3.3-5 V supply
- DO - digital output (threshold set by the trimmer)
- AO - analog output
- PCB size: 30 × 15 mm
- probe: 60 × 20 mm
- guide: 20 cm

During continuous measurement, the service life of the probe is greatly shortened, since the electrolytic reaction takes place here. For optimal probe and battery life, program periodic measurements with immediate result evaluation.

The product is not a stand-alone unit, it requires professional installation.
