After the module enters the alarm state, it will keep the alarm state and will not switch to other states. It needs to be powered on again to exit the alarm state. 2. If the sensor is exposed to high concentrations (above 10000ppm) of R290 gas, the sensor may be damaged and its performance may be affected. 3. The module fault signal takes priority over the alarm signal. Sensor basic testing circuit The module uses an MP511D sensor, and Figure 3 shows the basic testing circuit of the MP511D sensor. The sensor requires two voltages to be applied: heating voltage (VH) and testing voltage (VC).

Zhengzhou Winsen Electronics Technology Co., Ltd www.winsen-sensor.com Figure 3 Basic Test Circuit of MP511D Sensor Among them, VH is used to provide a specific operating temperature for the sensor, and the voltage is applied to both ends of the heating electrode using a DC power supply. VC is used to measure the circuit's loop voltage. VRL is the voltage on the load resistor (RL) connected in series with the sensor, which is the output voltage VOUT. The module determines the concentration of refrigerant R290 in the current environment by detecting the voltage of VOUT. On the premise of meeting the electrical characteristics of the sensor, VH and VC can share a common power supply circuit. Cautions Please do not put the module in organic solvent (include silica gel and other cementing compound), painting, medicament, oils and fuels, high concentration gas etc. Please do not impact or vibrate the module seriously. Please warm up for 5 min before first use. Please do not use the module related with personal safety. Please do not install the module in the severe convection environment. Please do not put in the module in high concentration organic gas for long time. Please supply the module with requested voltage as manual strictly, if voltage is higher than 5.5V, the module will be destroyed irreversibly.
