Infrared Obstacle Sensor Module Frequency & Distance Adjustment
This Infrared Obstacle Avoidance Sensor returns a signal when it detects an object in range. The range of the sensor is around 2-40 cm is 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. The 3 pin version does not have the ability to be enabled/disabled. The 4 pin version has optional Enable pin. Infrared obstacle avoidance sensor is designed to detect obstacles or the difference in reflective services. One application is to help a wheeled robot avoid obstacles with a sensor to react to adjustable distance settings. This device has an infrared transmitter and receiver, that forms the sensor pair. The transmitter LED emits a certain frequency of infrared, which the receiver LED will detect.

Digital Thermal Sensor Module Temperature Sensor Module
- 100% Brand New and High Quality
- the thermal resistance of the module is very sensitive to the ambient temperature , generally used to detect the ambient temperature ;
- through the adjustment of the potentiometer , can change the temperature detection threshold (ie, temperature control value) if necessary to control the ambient temperature is 50 degrees , the module in the corresponding ambient temperature to which the green light , DO output is HIGH level falls below the set temperature value, the output is high , the green light does not shine ;
- DO output can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting the ambient temperature changes ;
- DO OUR outputs can directly drive the relay module , which can be composed of a thermostat to control the operating temperature of related equipment can also be connected to the fan used to heat and other ;
- the detection range of the module’s temperature 20-80 °C ;
- this module can also be replaced with a wire temperature sensor for water temperature, water tank controlled.
