Thyristor driving circuit
This circuit is composed of the novel pyroelectric infrared sensing specific device TDH98072. This control circuit has the advantages of simple circuit, easy to adjust and high reliability. And this device can be used to assemble other control circuits such as the anti-theft alarm, the automatic control lights and the automatic water valve.etc. The photoconductive resistance CdS uses the light resistance which is lower than l00kΩ or the dark resistance which is higher than 3.3MΩ. The pyroelectric infrared sensor PIR can use any kinds of small pyroelectric probe such as the ANM1 type.
