Winsen

Winsen develops gas sensors and measurement modules for equipment integration. Specify the target gas, complete model and output interface when requesting supply through SpareX.

Models

MH-Z19C is an NDIR CO₂ module with UART and PWM outputs. MH-410D is an industrial infrared CO₂ sensor with UART and analog output; its range and power connection requirements must match the selected version. ZE07-CO is an electrochemical carbon monoxide module with a 0–500 ppm range. MQ-2 is a semiconductor sensing element for combustible gases and smoke, requiring a suitable external measuring circuit.

Legacy equipment

The manufacturer marks MH-Z19B and MG-812 as discontinued. An archived data sheet does not establish current availability. Replacement requires checking the pinout, supply, signal levels, calibration procedure and instrument firmware.
