Module Applications: Gas may be used in homes and factories leakage monitoring device suitable for the detection of gas. Butane, propane, methane, smoke, ... moreetc. Module Features: 1. Using high-quality dual-panel design, with power indicator and TTL signal output instructions; 2. The switching signal having a DO(TTL) output and analog output AO; 3. TTL output valid signal is low. Low-level signal when the output light can be directly connected to the microcontroller or relay module) 4. Analog output voltage with the higher concentration of higher voltage. 5. A gas, natural gas, city gas, smoke better sensitivity. 6. There are four screw holes for easy positioning; 7 Product dimensions: 32(L) 20(W) 22(H) 8. Has a long life and reliable stability 9. Rapid response and recovery characteristics Electrical properties: Input voltage: DC5V Power consumption( current) 150mA DO output: TTL digital 0 and 1( 0.1 and 5V) AO output:0.1-0.3 V( relative to pollution) The maximum concentration of a voltage of about 4V Special note: After the sensor is powered. Needs to warm up around 20S, measured data was stable, heat sensor is a normal phenomenon, because the internal heating wire, if hot is not normal. Wiring: 1. VCC: positive power supply(5V) 2. GND: power supply is negative 3. DO: TTL switching signal output 4. AO: analog signal output WE PROMISE YOU CAN GET THE ITEMS YOU PAID OR REFUND. To USA: Send by e-package.

Performance and highlights: 1. Voltmeter wide range DC4.5 ~ 40V. 2. 5V/ 2A output current(Only when the input voltage is 6.5 ~ 40V. It can output 5V) ... more3. A key(Output Enable" button) switch USB output. A key(low-power" button) to enter the ultra-low power. 4. Voltmeter can be artificially calibrated. Will never exist voltmeter inaccurate problem! 5. With reverse polarity protection. Reverse polarity does not matter. 6. With over-current. Over-temperature protection. 7. With USB power indicator. 8. Equipped with terminals to facilitate wiring. 9. High efficiency. Low ripple. 10. Size: L 58mm W 21mm H 10mm 11. Weight: 13g Instructions for use: Module is connected to power. The voltage can be detected in real time.When you need the phone, IPAD, MP3 and other digital products charge, click the"Output Enable" button,then USB power indicator lights, USB output voltage 5.0V.When you need to turn off the voltmeter, click the"Low Power" button, then enter the ultra-low-power standby mode, USB output corresponding shutdown. Applications: Wide input voltage. For car/ battery car/ motorcycle used for monitoring battery voltage; measure the voltage needed for a variety of occasions. The output current capability 5.0V/ 2A. Enough to meet a variety of USB devices, voltage is very stable. Voltmeter calibration method: Step 1. Press the"Output Enable" button more than 2 seconds. Release, voltmeter flashes, this time into the voltage regulation mode; Step 2. Press the"Output Enable" button(normal speed) the voltage value is adding up a unit; Press the"Low Power" button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the button, depending on the current display voltage, the higher the voltage, the fewer the number of press. Step 3. Press the"Output Enable" button more than 2 seconds. Release, to exit th
