The GP1A57HRJ00F sensor is mounted on a breakout board with a resistor which has pin headers which allows for easy breadboard attachment. This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. This module comes with both the IR optical interrupter and the breakout board.
This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins ground, power and analog voltage output that are broken out with a 0.1″ spacing, making the board compatible with 0.1″ headers and standard breadboards and perfboards. This board has two mounting holes and provides convenient pads for mounting the gas sensor s required sensitivity-setting resistor.
The MCP9701A is an analog temperature sensor which has a measurement range of 0 to +70 Degree C.
This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 10,000 ppm. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
This semiconductor gas sensor detects the presence of methane (CNG) gas at concentrations from 300 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
This breakout board is the simplest way to create a project with a single “momentary” capacitive touch sensor. No microcontroller is required here – just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the built-in one isn’t suited to your project.
