features : The use of the company's production of SW-420 normally closed type vibration sensors. comparator output signal clean wave well, driving ability, 15mA rated voltage and 3.3V-5V Etc.
The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer. When this no vibration, this module output logic LOW the signal indicate LED...
The RM0435 is an integrated Hall Effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be...
