ST’s VL53L5CX is a very small 8×8 grid ranging sensor that can perform distance measurements at a distance of up to 4 meters. In a recent video,[Henrique Ferrolho] demonstrated that ...

Abstract: This paper evaluates the sensing performance of photodetector in response to different colours of light sources used for water turbidity measurement. Initially the best photodetector is ...

Abstract: The cleanliness of a water body can provide important insight on the health of the ecosystem. Turbidity is a measure of the relative clarity of a liquid; the less light that can pass through ...

A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...
