LDR Sensor Module - Photosensitive Light Detection Sensor Module Bluetooth The TTP226 is an 8-Channel

The TTP226 is an 8-Channel Touch Sensor

The amount of time the Echo pin remains high is measured by the controller and the distance traveled by the wave is calculated by multiplying with the speed of sound and hence the distance of the object from the sensor is measured by halving the distance traveled by the wave

SWIM interface and reset button

Used in safety circuits to disconnect the load from supply in event of failure and much more

LDR Sensor Module - Photosensitive Light Detection Sensor Module Bluetooth The TTP226 is an 8-ChannelAmbient light sensing is a significant part of many applications like automatic street lights, solar panels charging controller, automatic irrigations systems where humidity and ambient light determine if the planet needs to be irrigated or not. We usually use a simple Light Dependent Resistor (LDR) as it changes its resistance with the amount of light falling over it, which gives us an idea about the light intensity in the surrounding. But in some
