Color Sensor Recognition Module is made of TCS3200 IC, a programmable colour light to frequency converter. Module consists of silicon photodiodes and current to frequency converter. Output of the sensor is square wave having 50% duty cycle. Frequency of the square wave is directly proportional to light intensity. Colour Sen
Flex Sensor is used to detect bends in one direction. Flex sensors are available in 2.2, 4.5 inches. For best outcomes, securely support the base and bottom portion and only let the actual flex sensor to bend. While using the flex sensor, make sure that the flex sensor should not bend beyond the usable range.
The force sensing resistor detects force or the pressure applied. This sensor is basically a passive component which causes a decrease in resistance when an increased force is applied. Two pins come from the bottom part of the sensor which has a 0.1” pitch. At the other end of the sensing area, the FSR mounts a peel and stick rubber. Res
Human ear hears sound frequency of 20Hz-20KHZ. Ultrasonic is the sound wave beyond 20 KHz. Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit.
DHT11 is a humidity and digital temperature sensor. It comes under the classification of weather sensors. The sensor gives out a digital signal based temperature and humidity output. DHT11 consists of an NTC, 8 bit microcontroller and resistive sense of wet components.
DHT11 calculates humidity by measuring resistance between the electrodes
