How to use Widg-X
Introduction
๏ปฟWidg-X is HavenTechnik's entry point IoT application platform. The module provides a basis on which to develop a standalone IoT application which reports to a standalone mobile device as a host. It further facilitates an integrated approach to IoT node development enabling multiple nodes to be integrated via a Wi-Fi network.
Modes of Operation
๏ปฟWidg-X has three modes of operation:
- Untethered: Configured, operates with no intervention or reporting.
- Wired: Configured, then run in proximity to a laptop or desktop. This mode is best suited for development or testing
- Wireless: Connected to either a Wi-fi or Bluetooth network. This offers real time reporting and monitoring of the target application.
Inputs and Outputs
The Widg - X offers both digital and analogue I/O. The digital I/O enables in contact interaction with the environment, and the sensory capability enables the detection and measurement of the ambient environment.
Digital
- 2 Digital inputs: Actuated by closing the two pins, effectively bringing the opto isolator to ground.
- 1 Relay: Actuated in software, the relay switches between normally closed to normally open either opening or closing the device under supervision, depending on the configuration.
Analogue
The basic analogue input allows for an LM35 to be connected. There is no input buffering or conditioning circuitry onboard, any signal conditioning would therefore need to be done external to the board.
Sensors
The unit is capable of integrating the following sensors:
- Analogue: LM35 (or similar device)
- DHT-11: Measures temperature and humidity.
- BME280: Measures temperature, humidity and air pressure.
Communications
The user has the option of:
- Wired: USB cable to PC
- Wireless: AI Thinker, WIFI | Bluetooth module
