What is the best way to vary the sensetivity of an IR Sensor pair using IR LED and TSOP1738 ?
First of all, I want to know what is the maximum practically achievable range using the above sensor pair.
A circuit which can reach this range will be great, alongwith code incase microcontroller is used.
Secondly, I want to know how I can reduce this range as I want.
For example, if IRLED + TSOP1738 can work till 1meters, I want to know how I can reduce this range to 5cm, 6cm and so on...
