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...
This is a breakout board for Analog Devices analog 3 axis accelerometer. The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs....
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...
