measurements temperature by diode 1N4148

temperature by diode 1N4148 and IC741.
easy to make and use.
Out to Voltmeter.
*** Low cost too !

When I wants the circuit takes the temperature to are simple. I uses Diode 1N4148 be formed check the temperature. By when feed voltage change it. It is have current flow be stable. When the temperature that Diode, change make Voltage. At it modifies with VR1 and VR2 fine decorate for show that is correct most fining decorates. The important I uses the temperature certainly compare with accurate temple. By compare with reserve 0 the degree Celsius per 0 Volt. For the certainty advises that, should use Digital Voltage Meter. Show well almost forget the important point should. Give power supply Regulator high-quality , such as IC 7815 and IC 7915 etc. Try usable this circuit sees, regard good base of the circuit takes the temperature sir.

Car Water Temperature by CA3161 CA3162
The circuit measures the car water temperature. CA3161 , CA3162 is a counter and 7segment driver to display amount of temperature on 7segments. The temperature sensor is a diode, 1N4148. This is s ...
Thermal Fan Controller by IC 741 and Diode
The controller uses one or more ordinary silicon diodes as a sensor, and uses a cheap opamp as the amplifier. I designed this circuit to use 12V computer fans, as these are now very easy to ge ...
