MPU-9250 9-DOF 3-Axis Accelerometer Gyro & Magnetometer
MQ135 Gas Sensor
MQ3 Module Gas Sensor
MQ4 Gas Sensor
MQ9 Module Gas Sensor
- DO switching signal (TTL) output and AO analog signal output.
- TTL output valid signal is low. (When the output low signal is on, it can be directly
- connected micro-controller or relay module.)
- Analog output voltage: the higher concentration, the higher voltage.
- Four screw holes, easy positioning.
- Long life and stability, quick response and resume.
- Input voltage: DC 5±0.2V
- Power: 150mA
- DO output: TTL digital 0 and 1 (0.1 and 5V)
- AO output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V.
- Dimensions: 32(L) * 20(W) * 22(H) mm
- AO – analog signal output
