Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

Next, I wired up AHT10 sensor module and Arduino Uno as shown in the below hardware setup diagram. I also uploaded a simple test code to display sensor readings on the Serial Monitor window. I got ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

Adding a photoresistor (light sensor) and a thermistor (temperature sensor) and connecting them to a programmed Arduino gave me a gadget that monitors the environment of a single plant. You can ...
