| please give me introduction about low voltage alarm?send to my e mail... | ||
| i want to have the circuit operation of the low voltage alarm and the it's output waveform immediately...and also i want to know what is the low voltage alarm?oscillator or 555 timer? | ||
| i want the Pcb lay-outs of low voltage alarm | ||
| What value resistor would I need to use to replace the 5k pot so it will trigger at 11V? I am trying to make it a little lighter and smaller. Thanks | ||
| 4mv/100c 140 degrees C is when I want it to trigger so about 6 mv i need it to trigger a relay | ||
| I'm looking to make a shutdown switch for a truck. Using a very low voltage coming from the exhaust thermocouple. What modifications to this circuit should I make. I think the voltage is less than .5volts and a very small range to the desired shutdown | ||
| .im interested in this kind of project.. please send me more info. and i want to know if i need to make some adjustments for it to work. please... | ||
| the circuit not working why ? | ||
| it woks | ||
