Soil Moisture Sensor (hygrometer) for Arduino LM393 assembled on a chip and has a separate sensor and the sensitivity setting.
Between the two electrodes Sensor creates a small voltage. If the soil is dry, the resistance is high and current is less. If the ground is wet - less resistance, and the current - more. On the final analog signal can be judged on the degree of humidity. Soil Moisture Sensor gives the output 1 or 0, depending on whether there is sufficient moist soil. Works soil moisture sensor (hygrometer) for Arduino as follows: first nastraevaem it to the desired humidity (tighten up resistor). Then, if the humidity is above the threshold, the sensor outputs a low level if it is lower, then high.
Use soil moisture sensor (hygrometer) for Arduino for the control of household flowers in greenhouses, etc. Can serve as a sensor for automatic irrigation systems.
The package includes:
- hygrometer, soil moisture sensor;
- sensor YL-69;
- connection 5-pin cable.
