MQ-5 Methane LPG Liquid Propane Gas Sensor Module – Arduino

Description

Model: MQ-5
– With the signal output instructions
– Dual output (analog output, and TTL-level output)
– TTL output valid signal is low (Low signal when the output light can be directly connected to the microcontroller)
– Analog Output: 0~5V, the higher the concentration the higher the voltage.
– High sensitive with liquefied petroleum gas, methane, coalgas
– Heater voltage: 5 +/- 0.2V (AC / DC)
– Working current: 150mA
– Loop voltage: – Load resistance: 1K ohms (adjustable)
– Detection concentration range: 300~5000ppm
– Clean air voltage: – Sensitivity: >/= 3%
– Response time: – Recovery time: – Element power consumption: – Working temperature: +10’C~50’C
– Working humidity: 95%RH (nominal humidity 65%)
