Simple Temperature Monitor Circuit - for ex le by 12 volts power supply the r1 is 2 2 k while r2 is 680 the maximum current consumption of the temperature monitor circuit when the led lights up is 20 ma take nothe that the t2 must not be e hotter than 125 0 c simple temperature monitor circuit when the voltage of the battery is more than 9 volts then the voltage on base emitter terminals will be same this temperature monitor is practical to monitor the level of heat from its power transistors and heatsinks and if needed to automatically turn off the lifier to avoid damage to the vital ponents the maximum current consumption of the temperature monitor circuit when the led lights up is 20 ma take nothe that the t2 must not be e hotter than 1250c take nothe that the t2 must not be e hotter than 1250c a simple indication whether the temperature value exceeded a maximum level or went below the minimum level is sometimes enough the.

circuit here does just that it indicated the temperature level about 25 o c 77 o f or below 20 o c 68 o f by lighting one of the two leds the temperature sensor is an ntc resistor coupled to two parators the temperature monitor circuit works by paring the voltage drop of a cold diode t1 with the base emitter voltage of a warm transistor t2 the transistor must be attached physically closest to the heat source ideally it should be attached to the heatsink of the power transistors when you select no external sensor the open circuit flag in the adt7461 register activates and the alert interrupt output asserts you can expand the system to include as many external temperature sensors as you require the limiting factor on the number of external sensors is the time available to measure all temperature sensors if you require two wire serial control of the multiplexer you can use this is the simple.

temperature monitor circuit diagram this temperature monitor is practical to monitor the level of heat from its power transistors and heatsinks and if needed to automatically turn off the lifier to avoid damage to the vital ponents operating temperature of transistor bc547 is up to 150 degree c so it can be perfectly used at high temperature as a heat sensor and we can also make a fire alarm out of it and we can also make a
