Hello,

I'm using LM35 for a fire detector project but I can't decide whether I should use a capacitor between the sensor and pic16f877 adc pin to minimize noise. The sensor is going to be placed very close to the pcb (about 10 cm or so) so I'm not sure. Also, I'd like to have recommendations on mounting options for the sensor. Do I need to a special enclosure or should I just "hang" it off the detector box? It is in TO-92 package and used for detecting the room temperature.

Thanks in advance
