ESAW Simple Circuit Modules, PCB Mounted (EEC-10322)

These simple circuit modules are intended to be used by the students to explore and familiarize with the applications of electrical / electronic components and devices, and simple circuits. All modules have components directly mounted on a rectangular PCB board, with soft cushioned feet at the bottom and have 4 mm sockets for connecting the modules in a circuit using leads. Supplied without connecting leads. Various modules available are:

EEC-10322 : Light Dependent Resistance {LDR) Board: Resistance varies with intensity of light falling on the unit. 

EEC-10322 : Light Dependent Resistance {LDR) Unit Accluster of three LDRs, connected in parallel, to provide increased sensitivity and better control of current directly in a reed relay.

EEC-10322 : Thermistor Unit: A cluster of five thermistor units, connected in parallel. [Ey

EEC-10322 : Push Switch: A simple ON/OFF push switch for opening or closing the circuit. [J

EEC-10322 : Single Pole, Double Throw (SPDT) Switch: A two way rocker action switch providing frequent change over between two circuits or connection /disconnection of a circuit. [Ej

EEC-10322 : Reed Switch: A heavy duty O N / O FF reed switch protected by series resistor against short- causes it to switchs” 6

EEC-10322 : Reed Relay: Current flowing through the coil produces magnetism to cause the reed to switch another circuit; the reed contacts being protected from short circuit damage by a low value series resistor{l))

EEC-10322 : Buzzer:1 A low current, low voltage DC, piezo-electric buzzer. EE]

EEC-10322 : LED Board: Large, light emitting diodes with a resistance connected in series, for potential differences of up to 6 V. available in Red/Green LED s.

EEC-10322 : Motor: A low voltage DC motor with series resistor to limit current consumption.

EEC-10322 : Moisture Sensor: For detecting the moisture through the changes in potential difference across the grid.

EEC-10322 : Resistors

EEC-10322 : Power Transistor
