Weike Electronics is a professional manufacturer and exporter that is concerned with the design, development production and marketing of arduino, 3d printers, raspberry pi and STM32. Our Dream is to make the best price and best quality produce for customers. So we would like to receive your valuable suggestions for our products and we can improve them for you.
Suitable for home or industrial on LPG, natural gas, coal gas monitoring devices. Excellent resistance to alcohol, smoke interference.
Module Features: 1, Using high-quality dual-panel design, with power indicator and TTL signal output instructions; 2, With a DO switch signal (TTL) output and AO analog signal output; 3, TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module) 4, The analog output voltage, the higher the concentration the higher the voltage. 5, For gas, natural gas has better detection sensitivity. 6, There are four screw holes for easy positioning; 7, Product Dimensions: 32* 20 * 22 8, With a long service life and reliable stability 9, Rapid response and recovery characteristics Electrical properties: Input voltage: DC5V power (current): 150mA DO output: TTL digital 0 and 1 (0.1 and 5V) AO output :0.1-0 .3 V (relatively clean), the highest concentration of voltage around 4V
