‘Things On Edge’ is a UK-based IoT company founded by Sylwester Bala and Piotr Lewandowski. Their aim is to help developers increase their productivity by providing them with easy-to-use, end-to-end technology, so that users no longer need to program IoT devices. Their flagship offering, IoT Cricket, has been recently featured in Practical Electronics, a premier electronics and computing maker magazine in the UK.

IoT Cricket is an ESP8266-based, easy-to-use Wi-Fi module consuming ultra-low power. It enables you to build various IoT devices in a few minutes, and power them directly on batteries, with literally no code and programming. In short, with IoT Cricket, you can:

• • connect devices to the Internet out-of-the-box, either from a smartphone or a laptop, using any web browser;
  • configure devices either locally or remotely;
  • integrate your devices into a huge IoT software ecosystem by using MQTT and HTTP communication protocols.

Key Features

• • Ultra-low power consumption, i.e. 0A current when not in operation
  • Operates directly on batteries below 3.5V (AA, AAA, etc.)
  • Configurable Analog or Digital inputs for sensors, buttons, and switches
  • Local configuration (directly on a Cricket Wi-Fi hotspot)
  • Remote configuration (from a TOE micro-service)
  • Configurable MQTT (using either a Things-On-Edge broker or any third-party MQTT broker)
  • Configurable secure / non-secure HTTP POST/GET requests
  • Configurable battery monitor
  • Built-in configurable Real-Time Clock (RTC) for regular wake-ups, with specified time intervals
  • Built-in configurable temperature sensor
  • Firmware updates

Below there are a few examples of what you can do with IoT Cricket:

• • Send notifications when someone is at your doorstep;
  • Ring your phone when someone presses a doorbell button;
  • Report the moisture levels in a flowerpot and raise an alarm on your phone when the moisture level goes below or above certain thresholds;
  • Report the temperature of a garden, home, room, etc.;
  • Report on the status of windows / doors, e.g. closed or open;
  • Report the triggering of your house’s alarm system, or just the detection of a suspicious move in a specified room, either by email or by ringing your phone;
  • Report noise detection.
  • There are literally endless application scenarios in relation to reporting data from any remote sensory devices.
