Q: What is the difference between sensor and module?

A:The sensor is a component, which requires the customer to do circuit design. The module is with circuit board and has been calibrated, which can save the customer's development time.

Q: How to calibrate the gas sensor?

A: Inject a specific concentration of uniform gas into a specific volume of closed test box, and the process of learning and memory of the gas sensor under this concentration is calibration. Different sensor calibration methods are different, simultaneous interpreting can be done for specific products.

Q: Why the sensor cannot be calibrated or does not alarm after it is made into a complete machine?

A: Sensor poisoning reduces the sensitivity. Generally, the whole machine materials (shell, cable, buzzer, rubber gasket, three proofing paint, etc.) and building decoration materials (all kinds of glue, putty, etc.) contain silicone or other substances that are easy to cause sensor poisoning.

Q: What model are the terminals of our products?

A: The specification of zh03b terminal is 1.25 * 8pin; The specification of mh-z19 series and ze08 terminals is 1.25 * 7pin; The specification of zph01b and zph02 series terminals is 2.54 * 5pin; The specification of zp01 and zp07 series terminals is 2.54 * 4Pin.
