Optoelectronic Applications using 741 and 555 Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12073
Indian Lab Suppliers supplies the Optoelectronic Applications using 741 and 555 (Product ID: 12073) as part of its electronics engineering lab equipment range. It is a training board for building sensor circuits with the 741 op-amp and 555 timer, using light and temperature sensors.
Quick Answer
The board carries a photodiode, phototransistor, LDR and NTC and PTC thermistors, which feed circuits built around two 741 op-amps and one 555 timer. Ten experiments are described: three 555 burglar alarms (wire break with LDR, phototransistor or photodiode), 741 LED and lamp drivers, NTC and PTC temperature ON-OFF controllers, and 741 burglar alarms with LDR, photodiode or phototransistor. An on-board ±12 V DC, 200 mA supply, transistors, potentiometers, a buzzer, a 6 V bulb and a set of resistors and capacitors allow other circuits to be designed as well. A 20 MHz dual-trace CRO and a multimeter are needed alongside.
