Giới thiệu Mô Đun Cảm Biến Khí Độc Mq-8 Mq8 tại Lotte Market
MQ-8 module Hydrogen sensor alarm Gas sensor MQ8 module
Module features:
1. Using high quality double panel design, it has power indication and TTL signal output indication.
2. It has DO switching signal (TTL) output and AO analog signal output.
3, the TTL output effective signal is low level. (when the output is low, the signal lights on, can be directly connected to a single chip or a relay module).
4. To simulate the output voltage, the higher the concentration, the higher the voltage.
5. It has good sensitivity to the detection of hydrogen.
6, four screw holes are easy to locate;
7. The shape of the product: 32 (L) *20 (W) *22 (H)
8. Long term life and reliable stability
9. Fast response recovery characteristics
Electrical performance:
Input voltage: DC5V power consumption (current): 150mA
DO output: TTL digits 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively pollution-free), the maximum concentration voltage is about 4V
