FC-28 Soil Humidity Detection Sensor Module

- This is a summary of the moisture sensor can be used to detect soil moisture, when soil water deficiency, the module outputs a high level, whereas output low level. Using this sensor to water the flowers make an automatic device, without people to manage your garden plants.

- Sensitivity can be adjusted (figure blue digital potentiometer adjust)

- Soil humidity module on the environment humidity the most sensitive, generally used to detect soil humidity

- Module in soil moisture can not reach the setting threshold, DO mouth output high level, when soil moisture more than setting threshold value, module D0 output low level

- Working voltage of 3.3~5V

- Has fixed bolt hole, convenient installation

- Small board PCB size: 3.2cm x 1.4cm

- Comparator using LM393 chip, work stability

Two small plate interface specifications (3 wires)

• VCC external 3.3~5 V
• GND external GND
• DO small plate digital output interface (0 and 1)

- Digital output D0 can be directly connected with the single chip microcomputer, through the single chip microcomputer to detect high and low level, thus to detect soil humidity

- Packing List:

• - 1 x Soil humidity sensor module
• - 1 x Soil sensor
• - 2 x Dupont cable (20cm)
