https://www.electronics-lab.com/news/sunburn-monitor-sound-base-indication-uv-monitor/
Sunburn Monitor is a UV monitor with sound-based indication. It calculates the max sun exposure before sunburn based on your skin type. The project was published over hackaday.io by [Quarterturn]. It’s based around SI1132 light sensor from Silicon Labs. SI1132 is a UV index and ambient light sensor with I2C interface and it’s available in […]
An isolated analog input for Arduino
https://www.electronics-lab.com/news/isolated-analog-input-arduino/
Giovanni Carrera designed a circuit that accepts input voltage from about 20mV to 5V or a current of 4 to 20 mA and converts it to a isolated frequency signal. A voltage to frequency converter can realize an opto-isolated analog input for Arduino or other microcontroller systems. This circuit is particularly suitable for industrial control […]
How to Measure LUX With Arduino
