current :<40 mA
The module based on DS1307
A LOW onthe master reset input (MR) clears the register and forces all outputs LOW
Notice that the number of zeroes is equal to the color's number as per the previous table
The reason for that is that we are looking to detect motion (change) not average IR levels
vibration and shock sensor acidity current :<40 mAIntroduction: The vibration sensor is used for sensing the impact force, shocks and vibration. It has high vibration detection sensitivity while suppressing background sound signal which affect vibration sensors . It is consists of piezoelectric element, spring oscillator, Sensitivity adjustment knob, and led. We can regulate the knob to adjust the sensitivity. For example when adjusting the knob clockwise, the sensitivity increases led will light
