Hi,
I am a final year engg student and we i am doing athe above said project. I am using a LHI958 PIR sensor. The sensor will basically detect the variation in the temperature in it's range and then if a warm body is detected then it will send a trigger signal to a digital camera uaing the PIC microcontroller and thus a picture will be taken. This project can be used in capturing images of wildlife in remote places. The problem i am facing is that the datasheets that i found are not much helpful. And the professors of my college have not worked with this sensor before. So currenly i don't have any guidance and hence my work is lagging. Could anyone please direct me in the proper direction. I have been able able to secure the circuit for the PIR sensor and amplification stage but i am still not comfortable with the working of the PIR Sensor itself. When i was testing the ckt. there was a variation in the voltage wen i placed my hand in front of the sensor. But it is very unstable. It fluctuates often. So if any of you has any prior knowlegde about this ckt. then i'll really appreciate it. Looking forward for a correspondence. Thank you. Have a nice day.
