ADJD-E622-QR999 is a high performance, small in size, cost effective light to voltage converting sensor. The sensor combines a photodiode array and three transimpedance amplifiers in a single monolithic CMOS IC solution. With a Red (R), Green (G) and Blue (B) color filters coated over the photodiode array, the sensor converts RGB light to analog voltage outputs, denoted by VROUT, VGOUT and VBOUT, respectively.

As mentioned before in this article there are many methods for capacity readout by microcontroller. Microchip offered us mTouch CSM module inside some of its products. In this article we will make detailed explanation of CSM module operation that will help you understand Capacitive touch CSM sensing example article.
Accelerometers and gyroscopes are used for various safety features in modern vehicles.Possible appliance of such sensor is very wide, from crash detection for airbag release to electronic stability control systems, allowing the car to aid the driver during evasive maneuvers at speed. Gyroscopes can also be used with navigation systems to provide fine location information and help when there is no GPS signal, e.g. in tunnels. We used this sensor in
SHT7x (including SHT71 and SHT75) is Sensirion’s family of relative humidity and temperature sensors with pins. The sensors integrate sensor elements plus signal processing in compact format and provide a fully calibrated digital output. A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap sensor. Example of this sensor usage with ATmega8 is given in this article.
