Digital Barometric pressure sensor is used to measure the absolute pressure of the environment. Hight of the robot or projectile can be measured using this sensor. For light detection, the Photoresistor sensor module is used. Night security light system uses this sensor with Arduino. The temperatur...

Photoresistors are used to indicate the presence or absence of light. It is also written as LDR. These are usually made up of Cds, Pbs, Pbse, etc… These devices are sensitive to temperature changes. So, even when light intensity is kept constant, change in resistance can be seen in the...
This project uses a light dependent resistor. When light falls on the LDR sensor, then the resistance of the sensor decreases, which lead to activate an alarm to give an alert to the user. This project is suitable in the application of providing security system for lockers, cash boxes which...
