Gikfun Capacitive Soil Moisture Sensor Corrosion Resistant for Arduino Moisture Detection Garden Watering DIY (Pack of 2PCS) EK1940

Q: Could you submerge the moisture sensor fully in soil if all connections are adequately protected?

I put conformal coating and heatshrink on them and had no problems with soil immersion. 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?

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?

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?

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<n;i++) { int raw = analogRead(SOIL_ANALOG); Debug << "Raw Reading: " << raw << "\r\n"; raw = max(SOIL_AIR,raw); raw = min(SOIL_WATER, raw); Debug << "MinMax'd Reading: " << raw << "\r\n"; a0 += raw; delay(5); } int reading = a0/n; float percentage = (reading - SOIL_WATER) * 100.0 / (SOIL_AIR-SOIL_WATER); return int(percentage); }
