I calibrate the sensors in water (100% moisture), and dry air (0% moisture) because there is lots of variation sensor to sensor in both offset and gain. **Q: What are the measurement units? Centibars?** A: You need to calibrate the units in code. More details here. https://wiki.dfrobot.com/Capacitive_Soil_Moisture_Sensor_SKU_SEN0193 **Q: What is the average power consumption per reading?** A: I don't know the answer, but it is pretty low. If interested, for the price buy one and see if it suits your needs. I use mine in a handheld device and only power it up when I need a reading. I am using a Raspberry Pico and running it off of a 9-volt battery reduced to 5 volts. **Q: What library do I need for a raspberry pi?** A: You don't need a library, just need to read the analog pin,A0. This is what I use: // Calibration: SOIL_AIR is reading when dry, SOIL_WATER is reading when submerged in water about 3/4 up the stick // Used to calculate a 0-100% range based on the readings #define SOIL_AIR 362 #define SOIL_WATER 637 int get_soil_readings(int n) { int a0 = 0; for(int i=0; i
