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.
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.
Thermocouples are best used for measuring temperatures that can go above 100 Degree C. This is a bare wires bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200 Degree C, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens. There’s a small piece of heat shrink on the end to keep the fiberglass from fraying. If you’re using at >250 Degree C temperatures, simply remove it with a small blade.
The A1301is a continuous-time, ratiometric, linear hall effect sensor. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field.
