A Raspberry Pi Pico combined with a BME280 sensor can create a small Pico Altimeter that measures data like elevation and air ...

Some hot days feel even worse thanks to high humidity, trapped heat and dew points. Cities are especially vulnerable.

ESP32 reads temperature and humidity from a DHT11 sensor and sends the data directly to InfluxDB Cloud. The web app (Flask) retrieves and visualizes this data using an embedded Grafana dashboard.

If you're looking to take the plunge into the world of ESP32 devices, then here's a basic overview of what you need to know.

Bottom Line The Phyn Smart Water Sensor is easy to install anywhere in your home and will tell you when you’ve sprung a leak and when your temperature and humidity thresholds are breached.

I appreciated the built-in temperature and humidity sensor, which helped me dress my mini tester appropriately.

Circuit and Working Fig. 2 shows the circuit diagram of the humidifier. The system is built around an Arduino Uno (MOD1), a 5V SPDT relay module, a humidity sensor (DHT22), an ultrasonic humidifier, ...

Raspberry Pi Rust driver for the DHT11 temperature and humidity sensor, compatible with the rppal GPIO library IoPin type. Based on this driver, but modified to work on my Raspberry Pi 4B ...
