Light Meter By LM334
This circuit is Light Meter, use IC LM334 is easy circuit.
Supply Volt 1.5-20V, Meter : 1mA.
PC1 = CdS Photocell or LDR.
If you are looking for Light meter circuit that good and easy. I inviting for to advise this circuit , because use IC LM334 (3-Terminal Adjustable Current Source) use easy. follow circuit picture. I uses LDR or PCI for detect the light and show the waymeter 0-1mA. By this circuit uses Voltage supply about 1.5V ( minimum ) arrive at 20V be regarded as use Voltage wide good period is sir.
