This is a quick post to show how to display soil moisture data from two different soil moisture sensors on the micro:bit screen. From left to right: grove soil moisture sensor (resistive), DF robot soil moisture sensor (capacitive), elecfreaks soil moisture sensor (resistive) The code below is for a micro:bit connected to a weather:bit andContinue reading “Measuring Soil Moisture with Two Types of Sensors”

Controlling Greenhouse Humidity with a Water Atomizer and Humidity Sensor
Here’s one way to create a feedback system that keeps the humidity level in your mini greenhouse consistent. This tutorial uses: 2 micro:bits 1 grove shield 1 grove water atomizer 1 sensor:bit 1 weather:bit 1 small computer fan 1 servo motor External power for the sensor:bit and grove shield, a standard micro:bit battery pack withContinue reading “Controlling Greenhouse Humidity with a Water Atomizer and Humidity Sensor”
