In this circuit, a sensitive PIN diode is used as a fire sensor for longer-range fire detection. 2) is used in the circuit as light and IR sensor. Normally, in ambient light condition, photocurrent from the PIN diode is very low; it keeps output of IC1 low. 2: BPW34 PIN photodiode A small solder point to which a thin wire is connected is the anode and the other one is the cathode terminal. How does a system respond to Sparks within cables. This process is used to prevent automated spam bots. It will conduct only when it … BPW34 is a 2-pin photodiode with anode (A) and cathode (K). The only problem is it uses 50ma in standby mode and 70ma when active. There are different types of flame detection methods. Here pin 6 is shorted with the Vcc pin 5 to get a fire force siren. So the input offset voltage due to the photodiode is very low in this self-biased photovoltaic mode. BPW34 is a 2-pin photodiode with anode (A) and cathode (K). Thermistor is temperature sensitive resistor, whose resistance changes according to the temperature, its resistance decreases with … A PIN diode is a diode with a wide, undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region. This indicates that the circuit has detected fire. The advantage of a PIN diode is that the depletion region exists almost completely within the intrinsic region, which has a constant width (or almost constant) regardless of disturbances applied to the diode. A photodiode is a PN-junction diode that consumes light energy to produce electric current. IC1 amplifies and converts the photo current generated in the PIN diode to the corresponding voltage in its output. The term PIN diode gets its name from the fact that includes three main layers. A fire alarm system is used primarily to evacuate the premises in the event or occurrence of a fire condition and then secondarily to report the fire to the proper authorities, in this paper basically a low cost fire detection and control system So visible light and IR from the fire can easily activate the sensor to trigger the alarm. Rather than just having a P-type and an N-type layer, it has three layers such as PIN diode based fire sensor. PIN Diode Based Fire Sensor.
