1
Q
What is an LDR
A
Light dependent resistor
2
Q
What does an LDR do
A
-it is dependant on the intensity of light
-in bright light resistance falls
-in dim light resistance increases
3
Q
What is a thermistor
A
A temperature dependent resistor
4
Q
What does a thermistor do
A
-in hot conditions resistance drops
-in cool conditions resistance increases
5
Q
What type of circuits use LDRs and thermistors
A
Sensing circuits
