DHT11 Temperature and Humidity Sensor Module IN Pakistan

The Digital Light Dependent Resistor LDR Sensor Module is used to detect the presence of light / measuring the intensity of light. The output of the LDR module goes high in the presence of light and it becomes low in the absence of light. You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know is the light present and decide what to do with it.LDR photoresistor sensor module comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides an LDR, high sensitivity and commonly being used for light detection.

Arduino KY-032 Obstacle avoidance sensor modules Infrared Obstacle Avoidance Sensor returns a signal when it detects an object in range. The range of the sensor is around 2-40 cm distance. It operates at 3.5 to 5 volts at around 20 milliamps. The Obstacle Avoidance Sensors usually come in two types – with 3 and 4 pins. This is the 4 pin version Sensor Module and has an optional Enable pin. An infrared obstacle avoidance sensor is designed to detect obstacles or the difference in reflective services.

Flame Sensor Module Fire Sensor Module infrared Receiver Ignition source detection module This tiny Flame sensor infrared receiver module ignition source detection module is Arduino compatible can use to detect flame or wavelength of the light source within 760nm~1100nm also useful for Lighter flame detect at the distance 80cm. Greater the flame, farther the test distance.
