Operating Temperature Range: -30°C to 70°C
8KHz (8bit) / 800KHz (4bit)/ (customizable)
1pcs Normally Closed Vibration Sensor Alarm Module
embedded arbitrary installation
This is a very common MOSFET with very low on-resistance and a control voltage (gate threshold voltage) that is compatible with any 5V microcontroller or mechanical switch
Infrared Barrier Sensor Module (Obstacle Avoidance) alarm clock Operating Temperature Range: -30°C toThe sensor module light is adaptable to the environment, it has a pair of infrared transmitting and receiving tube, tube infrared emit a certain frequency, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving tube, after the comparator circuit processing, green indicator will light up, at the same time signal output interface to output digital signal (a low level signal), can be through the potentiometer knob
