Touch Dimmer PCB Layout

Working Explanation

In the circuit diagram, the series network R2-C4-D1 provides a direct voltage of 5V directly from the mains to power IC1. The IC is also in sync with the mains voltage via resistor Ry and capacitor C2. The actual phase gating is effected by triac Tri, whose gate is linked to pin 8 (QT) of IC1 via diode D2. The phase-locked loop (PLL) of the IC is synchronized with the mains frequency via capacitor C3 and resistor R3.
The touch sensor that enables a domestic light to be dimmed consists of three 4.7 MS2 resistors, R3-R5.
These high resistance values make touching the sensor harmless. The output of the sensor is applied to pin 5 (SEN) of IC1. Since in some cases it is handy to control the circuit with a push-button switch, this may be connected between S and La on connector K1.

The IC also has an input lexT, which is for use with the optional infra-red remote control that is based on IC2, a Type SFH506-36. This circuit picks up the signal from the sender and converts it into a control signal for IC via a network that comprises among others, T1 and R7. The operation of the dimmer is determined by jumper JP1. When this is left open, the dimmer will always start with the brightness with which it was switched off. Each time the dimmer is started, the direction in which it is controlled is reversed.
When the jumper is placed to connect pin 2 of IC1 to C3, the dimmer always starts at maximum brightness. When the jumper is placed in the position shown in the circuit diagram, the dimmer always starts at minimum brightness.

The dimmer is best built on the printed-circuit board shown, which may be made with the aid of the track layout given in the Appendix.

It cannot be emphasized too strongly to bear in mind that the circuit carries potentially lethal mains voltages. Only connect the dimmer to the mains when it has been completed and built into an insulated or plastic case. If the infra-red remote control is not used, IC2 and T1 and associated components, except R7, may be omitted.

Operating Principle of Remote Controlled Touch Dimmer

The operating principle of touch dimmer using SLB0587 ic is based on the capacitance change principle, where the capacitance of a particular part of the circuit changes due to the introduction of a conductive object. In the touch dimmer system using the SLB0587 ic, two conducting elements are present, and a capacitive circuit is formed between them.

When a user touches the touchpad, the capacitance of the circuit changes due to the user’s conductive body, which is detected by the SLB0587 ic. The detected signal is then amplified and processed to generate the desired output.

The touch dimmer using SLB0587 ic uses a microcontroller that controls the signal processing and adjusts the output based on user preferences. The output can be either a PWM (pulse-width modulation) signal that controls the brightness of the light or a variable voltage signal that controls the fan’s speed.

Construction of Remote Controlled Touch Dimmer

The touch dimmer using SLB0587 ic consists of several components that work together to produce the desired output. The key components are:

• Capacitive Touchpad: It is the interface between the user and the touch dimmer system. It is constructed of a conductive material that allows the user to make contact with the circuit.

• SLB0587 ic: It is a universal capacitive touch sensing IC responsible for detecting the capacitance changes due to touch input.

• Microcontroller: It is a small computer on a single integrated circuit chip, which is responsible for controlling and processing the touch dimmer system’s signal.
