The temperature controller circuit for chicken farm consists of temperature detection circuit, temperature control circuit and temperature simulation display circuit, and it is shown in Figure 4-39. Temperature detection circuit is composed of the integrated temperature sensor ICl, operational amplifier integrated circuit lC2 (Nl, N2), the N3, N4 which are inside of IC3 (N3-N5), resistors Rl-RlO and potentiometer RPl. Temperature control circuit is composed of internal N5 of IC3, diodes VDl, VD2, dual time-base IC lC4, resistors Rl2-Rl5, light-emitting diodes VLll, VLl2, potentiometer R and relay K.
