Thermostat Controller

  • 6995

We currently have 1 in stock.

Description:

This module contains three Panasonic AQH3213 AC Solid State Relays. A Solid State Relay (SSR) is a voltage controlled switch. These three relays can control an HVAC system and can turn on and off the FAN, HEAT, and COOL. The module also contains a TMP102 Temperature Sensor. With this module you can set up a really great intelligent thermostat.

It also contains an EFM32WG842 Gecko low power microcontroller and two RS232 serial ports allowing it to be daisy chained in a network.

The TMP102 Temperature Sensor is accurate to 0.5°C/0.9°F over a range of -25°C to +85°C (-13°F to 185°F).

Features:

  • Three Panasonic AQH3213 AC Solid State Relay
    • 1.2A On-State RMS Current
    • 600V Repetitive peak OFF-State Voltage
    • Zero-Cross Type (Relay state changes only when the voltage crosses zero)
    • 5000 VAC Isolation
  • TMP102 Temperature Sensor
    • 13-bit Resolution
    • Readings to 0.0625°C resolution
    • Very low power

    • Low Power Operation
    • 32KB Flash Memory
    • 4KB RAM
  • MAX3232 Dual RS232 Line Driver/Receiver
  • 6 Pin DF11 Right Angle Male Connector for Programming and Debug
  • May be Programmed with the Arduino IDE
  • The FTDI USB RS232 Interface and USB Mini-B connector that is used to bring power to the module. It can also be used for programming and connection to a server.
  • Two RS232 interfaces connected to 4-pin DF11 connectors. These interfaces will supply +5V power and communication to other boards and/or a server connected in a home automation network.
  • A DF11 10-pin connector that can be used to add on a radio module for wireless control.
  • Three QRE1113 reflective object sensors that can be used for switches.
  • A 10-pin FPC connector that can be used to connect an LCD display.

Applications:

  • Home Automation - Thermostat
