I2C Soil Moisture Sensor
Description
- I2C Soil Moisture Sensor
- Features a "sensor mode only" version
- Provides ambient light and temperature readings
The I2C Soil Moisture Sensor is a "sensor mode only" version of the plant watering alarm Chirp.
Capacitive soil moisture sensor interfaced via I2C. Additionally provides ambient light and temperature readings. The sensor works fine with Arduino and RaspberryPi and is open-source hardware.
The sensor can be read via I2C protocol and provides these features:
- Soil moisture sensing
- Light sensing
- Temperature sensing
- Reset chip
- I2C address change
- Deep sleep
- 1x I2C Soil Moisture Sensor
- Version: 2.7.5
- Supply voltage: 3.3 - 5 V
- Operating temperature: 0 - 85 °C
- Moisture reading drift with temperature: - <10% over full temp range
- Default I2C address: 0x20 (hex)
前回は2年前に購入し、連続して測定した結果、動作不良を起こしたため、再購入した。
研究用センサーに比べ測定値が土壌塩分に影響されていると思われるが、同一地点での相対的な水分変動は十分に反映しており、実用性が高い。
このセンサーよりローコストなCapacitive soil moisture sensor(V1.2)より測定値が安定しており、長期間の使用に耐えた。
研究用センサーが、このセンサーの数十倍の価格なので、非常にコストパフォーマンスが高い。
The product is the nearest thing that could come as a real soil moisture. Better than Adafruit. The delivery is really fast as well.
