Light monitoring system Project is measuring the intensity of light at a particular location with the help of light-dependent resistor (LDR ).Intrernal resistance of LDR changes with amount of light falIing on it. In darkness when there is less light falling on LDR, its resistance increases and in bright light, the resistance decreases.
Here we are going to measure the light falling on LDR and send this data over the internet to the cloud using bolt cloud.Connections
1. Insert one lead of the LDR to 3v3 port and other pin to A0 port in Bolt Module.
2. Insert one leg of 10k resistor to GND and other to A0.
NOTE: GND and 3v3 should not touch each other because it will short the module.
