Infra Red/Light/Colour
Infra Red Sensors
This is low cost LDR (Light Dependent Resistor). Basically it is a light sensitive resistor, the resistance will decrease when the surface is expose to light. It is widely used to detect Day or Night, example in automatic car porch light.
This HC-SR505 small body sensing module is based on infrared technology perfect to use in your sensing projects eg. alarm, motion camera etc
Next-Gen Occupancy Detection: More than just a motion sensor. The LD2410C is a high-sensitivity 24GHz millimeter-wave (mmWave) radar module designed for advanced human presence detection.
