An Arduino magnetic sensor has several uses: for reading the speed of a rotating object, for door alarms and for navigation. In this tutorial, we will build a simple magnet detector using a hall effect sensor.

In the previous tutorial, we set up a soil moisture sensor and have its data readable via WiFi. However, that data is only accessible if the NodeMCU ESP8266 and the client (smartphone, PC, etc.) is in the same network. In this tutorial, we will use a service that allows us …

Plants need enough water to survive. But what if you forgot to water the plants? This multi-part ESP8266 tutorial aims to provide a simple soil moisture sensor that reminds you, via WiFi, that your flora needs a shower.
