555 temperature interval control circuit
As shown in diagram 20-3, control circuit includes step-down rectifying parts and temperature control parts. It is used for keeping certainly temperature interval occasions such as poultry hatching, biotic experiment, etc. IC (555) works on the state of dual stable mode. RT is negative temperature factor thermistance (3kΩ), RT, R2~R4, RP1, RP2 make up control temperature divider voltage network. It can make pin 2, 6 of IC separately located in near 1/3VDD and 2/3VDD level by adjusting RP1 and RP2, in order to set or reset along with the changing of setting temperature (20℃~100℃), and it can pulled in or cut off J1, it can control the breaking over, cut off of electric heater, and it can adjust the temperature.
