## Description

Perfect for educational uses, the **Adafruit Simple Soil Moisture Sensor** is low cost, and easy to use. This is a simple *resistive* style moisture sensor, where there's two prongs and the sensor measures the conductivity between the two. Adafruit gold-plated the prongs so reduce risk of oxidation - if you see build-up on the prongs, clean them off with a dish-scrubber to keep the sensor going.

While not as advanced as a capacitive or frequency-based sensor, these are really easy to use! Adafruit are stocking this sensor for folks who want to use it with a micro:bit or Arduino or other board with an analog input. It won't work with a Raspberry Pi because those don't have analog inputs - [for that use a capacitive sensor](https://core-electronics.com.au/adafruit-stemma-soil-sensor-i2c-capacitive-moisture-sensor.html).

Getting started is super easy!

- **When using with a micro:bit** you'll need some [small alligator clips](https://core-electronics.com.au/small-alligator-clip-test-lead-set-of-6.html). Connect the GND pad from the 'bit to the GND pad on the sensor. Connect the 3V pad to the 3V pad. Then connect the 0 pad on the 'bit to the OUT pad on the sensor (you can also use 1 or 2 pad on the 'bit). Then, on the micro:bit read the analog value. When soil is dry, the reading will be under 100. As the soil gets wetter it will rise to 1000.
- **On an Arduino,** connect 3V to the 3V output pin (or 5V if there's no 3V pin) and GND to ground. You can either use [alligator-clips-to-pins](https://core-electronics.com.au/small-alligator-clip-to-male-jumper-wire-bundle-12-pieces.html) or a [JST SH to pins cable](https://core-electronics.com.au/jst-sh-compatible-1mm-pitch-3-pin-to-premium-male-headers-cable-100mm-long.html). Then connect the OUT to A0 or another analog input. When you use analogRead() you'll see dry soil at < 100 and wet soil > 600.
 
Either way, no soldering is required!

**Please note: This is just the sensor, you'll also need alligator clips or a JST-SH cable to connect to it!**
