KSCH4 Methane Sensor High Accuracy and Stable Performance with 100PPM Resolution

KSCH4 Methane sensor manual

Introduction

KSCH4 is a based on NDIR non-dispersed infrared absorption principle of gas detection module, adopt the dispersive air inlet. KSCH4 using porous inner light tube and casing outside the card slot, not only ensure the characteristics of air convection diffusion speed, and strong and durable, easy to install.

KSCH4 uses an imported light source and a dual-channel detector. Has the very good selectivity, no oxygen dependence, long life characteristics.

KSCH4 with UART, IIC digital output and analog output voltage (or the PWM frequency output mode), facilitating the clients to choose application; KSCH4 provide zero calibration, calibration and sensitivity of clean air relative zero calibration command, and to provide customers a manual clean air relative zero calibration MCDL pin, convenient to customers in the use of the free flow of clean outdoor air relative zero calibration of sensor module.

Feature

Wiring

Note: MCDL - Clean Air relative to calibration function pin

Precautions

• When the module is cold start, the warm-up time is not less than 2 minutes.
• Sensors should be calibrated regularly, recommended no more than 3 months.
• do not long-term use of sensors in dust dense environment.
• Please pay attention to the connection of the positive and negative electrodes of the power supply and the signal output end, do not reverse connection.
