TEMT6000 Sensor Features The TEMT6000 sensor is an analog sensor which has a function similar to NPN transistor. The sensor is designed to mainly detect the light spectrum visible to the human eye with peak sensitivity. If the light intensity increases or decreases, it will react properly. This sensor is too sensitive and react to slightest changes in a wide brightness range. Note This sensor does not react well to IR and UV light. You can download the datasheet of this sensor here.  [wpdm_...

IR Flame Sensor Features The flame sensor is actually an infrared receiver. In this module, the output of the infrared receiver is measured using a comparator IC. If the fire and flame (or any other infrared source) is close to the sensor, the output of the comparator is LOW, otherwise the output is HIGH. Note There is a potentiometer on board to change the sensor's sensitivity. In practice, this potentiometer changes the reference voltage of the comparator IC (the same voltage that the sensor voltage is co...
