Self watering system using a soil moisture sensor and water pump

Here’s one way to set up a self-watering system for a potted plant. For this version you’ll need: 1 micro:bit 1 sensor:bit 1 sensor:bit compatible relay 1 sensor:bit compatible water pump 1 soil moisture sensor (this tutorial uses the DF robot capacitive soil moisture sensor) I recommend starting by connecting your soil moisture sensor andContinue reading “Self watering system using a soil moisture sensor and water pump”

Simple weather:bit code: collect data and show on screen

This is a simple program that uses a micro:bit and weather:bit to sense soil temperature, soil moisture, environmental temperature, and humidity. It displays all of these values on the micro:bit screen. https://makecode.microbit.org/_6vY8THAjWJXy

Measuring Soil Moisture with Two Types of Sensors

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”
