The LDR has the highest resistance in dark around 1012 Ohm and this resistance decreases with the increase in Light. Light Intensity V/S Resistance As per the property of LDRs, the amount of light entering the LDR the inversely proportional to the resistance of the sensor, and the graph is...
The ultrasonic module is used for non-contact range detection. It makes use of sonar for its working. IR Infrared obstacle avoidance sensor detects objects which are before it and generates a digital signal. It is used in robots. Soil hygrometer is a soil moisture sensor. It generates a digi...
In our day-to-day life, we got used to implement different differenttypes of sensor circuitsusing various types of sensors such asIR sensors, temperature sensor, pressure sensor, PIR sensor, and so on. Frequently, we observe PIR sensor circuit based automatic door opening system, LDR sensor ci...
Insignal conditioning unit, the output of the sensor may be amplified, filtered or modified to the desired output voltage. For example, if we consider a microphone it detects the audio signal and converts to the output voltage (is in terms of millivolts) which becomes hard to drive an out...
