TSL2540 Ambient Light Sensor matches eye-response
https://www.electronics-lab.com/tsl2540-ambient-light-sensor-matches-eye-response/
ams (Graz, Austria) has posted details of the TSL2540, a very-high sensitivity light-to-digital converter. Evaluation kit is available: The TSL2540 is a very-high sensitivity light-to-digital converter that approximates the human eye response to light intensity under varying lighting conditions and transforms this light intensity to a digital signal output capable through a 1.8V I²C interface.

Making of a New Nixie Tube
https://www.electronics-lab.com/making-new-nixie-tube/
Dalibor Farny shows us how he hand make new Nixie tubes on this interesting video! The nixie tube is a vintage display device which had been used until 70s when it was replaced with LED displays. The complex knowledge of manufacture of nixie tubes literally died with tube factory’s engineers, glassblowers and machine operators. I […]
Arduino Weather Station with DHT11 and BMP180
https://www.electronics-lab.com/arduino-weather-station-dht11-bmp180/
In the previous tutorial I showed you how to build a weather station using only the DHT11 sensor and I said the readings from this sensor is fairly accurate. In this tutorial, I will be using the DHT11 to measure only the humidity and BMP180 to measure pressure and temperature. That’s because its readings are […]
