Description
The purpose of the demonstration board is to promote the various types of applications where a single AC switch is controlled in on/off full-phase mode. The switch control is based on information from a single sensor evaluated by an MCU. STEVAL-IHT004V1

Features
■ 3 independent application programs – Hand dryer with infrared sensor and T1235H-6T switch – Bathroom fan with humidity sensor and ACS108 switch – Multi-entrance room controller with push button and BTB08-600SW switch
■ Two potentiometers for setting sensor sensitivity and TRIAC turn-off delay
■ Capacitive power supply (680 nF capacitor EPCOS B32923C3684 – 5 V ±10% – Average output current: 16 mA – Standby power losses < 0.3 W @ 230 V
■ Program selector (U2)
■ ICC connector for software adjustment
■ Free development area with hole matrix available for application breadboard adaptation
■ Overvoltage protection is not implemented on the board but some solder pads are available to implement it in two different ways:
■ Varistor addition between mains voltage
■ Transil addition between TRIAC A2-G terminals
■ RoHS compliant
