We all know that plants require sunlight for their healthy growth. However, at times we may not be able to keep a track of it or maybe we are not sure if our plants are getting enough sunlight. hence this project ensures that the plants get proper sunlight.
LDR seems to be pretty simple. They sense the light, just like a thermometer senses the temperature, and a speedometer senses speed. Temperature and speed are easy to comprehend because we sense them in a straight-forward way. But light is very complicated. Temperature and speed are intensive properties, so they don’t depend on the mass or size of an object.
LDR senses the light as analog value hence we have to connect the LDR with the A0 pin of the BOLT WIFI module so the analog output value of the LDR is given as the input to the ADC pin of BOLT WIFI module( where A0 pin = ADC pin)BUILD THE CIRCUIT:-
STEP 1:- Make sure that the module is not connected before we connect the circuit to avoid short circuit.
STEP 2:- Connect one end of the LDR pin with the A0 pin of the bolt wifi module
STEP 3:- Connect another end of the LDR pin with the 5v pin of bolt wifi module
STEP 4:- Connect the resistor with the gnd pin of bolt wifi moduleTHE RESULT IS SHOWN BELOW VIDEO
