Infra Red/Light/Colour
Infra Red Sensors
Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. The SHT41 sensor is the fourth generation of I2C temperature and humidity sensor from Sensirion.
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.
