This CCS811 Air Quality Sensor Breakout Board can measure the eCO2 (equivalent CO2) and TVOC (Total Volatile Organic Compounds) density. It can be widely used in many applications, such as air qual...

Through it, you can control a circuit of high voltage with low voltage, say 5V on the controller. There is an indicator LED on the board, which will light up when the controlled terminals get closed.

The resistance of photoresistor decreases when the intensity of light increases. A dual OpAmp chip LM358 on board produces voltage corresponding to intensity of light(i.e. based on resistance value...

The sensor consists of an IR LED and a photo sensor (phototransistor). The light emitted by the IR LED gets reflected by any object placed in front of the sensor and this reflection is detected by ...

An infrared LED is like any other LED, with its color centered around 940nm. We can not only use the emitter to transmit data or commands, but also to emulate remotes to control your home appliance...

It has a low power consumption digital chip LSM6DS3 and power supply regulator which features high sensitivity and low noise interference. It can be configured to different levels of sensitivity to...

Science teachers who want to bring an inquiry-based, hands-on approach to their middle school classrooms can enable their students to think and act like real scientists with the Science Kit Physics...

Compared to LCD, OLED screens have a number of advantages such as high brightness, self-emission, high contrast ratio, slim / thin outline, wide viewing angle, wide temperature range, and low power...
