74HC191 (4-Bit Counter) idler pulley it first intercepts one half

it first intercepts one half of the PIR sensor

When no pressure is being applied to the FSR its resistance will be larger than 1MΩ

Note: We have tested this module in Future Electronics (Arduino Egypt) site with one tranceiver indoors and the other one outdoors and the communication distance was more than 85 meters

74HC191 (4-Bit Counter) idler pulley it first intercepts one halfThe 74HC191 are asynchronously presettable 4 bit binary up down counters. They contain four master slave flip flops with internal gating and steering logic to provide asynchronous preset and synchronous count up and count down operation. Specifications Synchronous reversible counting Asynchronous parallel load Count enable control for synchronous expansion Single up down control input Output capability: standard 74HC191 datasheet
