First of all, I have a mental block when it comes to circuits for whatever reason. I can build my own computer, I built my own network in my house, and I'm ...

An IoT demo project using ESP32 to send sensor data (humidity, temperature) to a Raspberry Pi via MQTT. Node-RED is used for data visualization and control. Secure communication is enabled with SSL, ...

The project is completely open source and based on a Raspberry Pi base station which connects to ESP32 based sensor nodes and online services to nicely present the data on a 7″ touch screen display.

The aim of this project is to build a device capable of monitoring the temperature and humidity of its surroundings using a Raspberry Pi Pico, a 16x2 LCD screen, and a DHT11 sensor. The project ...

Raspberry Pi enthusiasts may be ... The SHT31-DIS-B is a Humidity and Temperature Sensor builds on a new ... TCS34725 – This device provides a digital return of red , green ...

– DHT22 — This temperature and humidity sensor has temperature accuracy of +/- 0.5 C and a humidity range from 0 to 100 percent. It is simple to wire up to the Raspberry Pi and doesn’t require any ...

Seeking data on how well the appliance works, [Matthias] wired a DHT22 temperature/humidity sensor to a spare Raspberry Pi to monitor room conditions, and plugged the dehumidifier into a Kill-A ...

Node-RED could be the software tool to best enables Raspberry Pi run for Internet of Things projects.
