Product Description:
YJJ MMD1001E MMD1001E Electrochemical Formaldehyde Gas Sensor Module Is Used for Environmental Monitoring
Features:
I. Product description
MMD1001E
The E - type electrochemical formaldehyde module is a general - purpose and miniaturized module. Using the principle of electrochemistry
The presence of CH 2O in the air for detection has good selectivity and stability. Built-in temperature sensor,
Can be temperature compensation; With digital output and analog voltage output mode, easy to use.
MMD1001E is designed and manufactured by combining mature electrochemical detection technology with sophisticated circuit design
Out of the general gas module.
Two, module characteristics
High sensitivity, high resolution, low power consumption, long service life
UART Data output mode
High stability, excellent anti-interference ability, temperature compensation, excellent linear output.
Three, the main application
Portable instrument, air quality monitoring equipment, air purifier, fresh air ventilation system, air conditioning,
Smart home devices and other places.
Main parameters of the MMD1001E electrochemical formaldehyde gas sensor module are as follows:
Core parameters
Detection range: Generally covers 0 - 1000 ppm (the specific range should be referred to the product manual)
Output signal: Current or voltage signal, proportional to the gas concentration.
Response time: Several seconds to several tens of seconds (The exact speed is affected by the rate of gas diffusion)
Notes for Attention
Preheating requirements: After power-on, it needs to preheat for about 20 seconds to ensure stable data.
Environmental impact: Sensitive to temperature. Calibration should be performed under the guidance of the manual.
Life limit: Failure may occur due to the depletion of the electrolyte or electrode poisoning.
