Overview
Electronic brick of soil moisture sensor is mainly used to detect the moisture content in the soil. The control board can get the moisture value or threshold in the soil via analog or digital pins.
Features
1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.
3. With switch to shift between analog and digital output. Able to read the specific soil moisture information (analog) or the over-wet or over-dry soil information according to the threshold (digital). The adjustable potentiometer is used to set the moisture threshold.
4. With hysteresis comparator circuit for more stable digital output voltage.
