توضیحات بیشتر
1, using high-quality design PANEL double, with power meter and TTL output instructions;
2, with only a signal switch (TTL) output and analog output AO;
3, TTL output high and low. (can be directly connected microcontroller or relay module)
4, analog voltage output change with concentration.
5, liquefied petroleum gas, natural gas, city gas, smoke have better sensitivity.
6, there is a screw hole for easy positioning;
7, with a long life and reliable stability
8, quick response and resume
Electrical performance:
Input voltage: DC5V power (current): 150mA
DO Output: TTL digital 0 and 1 (0.1 and 5 V)
Output AO: analog signal level
Special Note: When the sensor is powered, heat needs to about 20 s measured data becomes stable, the heat sensor is normal, because the inside with an electric wire, if not hot normal.
Wiring:
1, VCC: positive power supply (5 V)
2, GND: a negative
3, do TTL output signal switch
4, AO: analog output
5, a fixed bolt hole for easy installation
