Gravity: Formaldehyde (HCHO) Sensor is a module for measuring the concentration of formaldehyde (methane) in the air. It can be supplied with voltage in the range of 3.3 ... 6V. DFRobot SEN0231

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.
