Description

The Things On Edge Cricket module is an easy to use, ultra-low battery powered Wi-Fi module. You can build various IOT devices within minutes and power them directly on batteries – with literally ZERO code & programming. You can connect devices to the internet out of the box either from a smartphone or a laptop from any web browser; Configure devices either locally or remotely; Integrate to a huge IOT software ecosystem by using both MQTT and HTTP communication protocols.

Details

Cricket is a highly power-efficient and user-friendly WiFi module. Without writing a single line of code, you can build various types of sensors, buttons & switches. You can transmit data over WiFi networks out of the box. What’s more, you can also integrate it with a huge software and internet service ecosystems by using MQTT and HTTP(S) protocols.

What is really cool is that it can be powered directly on batteries (e.g. AAA) for a really long time. In many use cases, it can run for years on single batteries. This is due to its hardware design of the deep sleep mode, which consumes as little as 0.5uA.

Cricket also comes with an optional FREE cloud service. You can choose to use COTA service to configure devices remotely if you wish. You can also choose to use a FREE MQTT broker as every Cricket comes with its unique account registered in the broker.

As the cloud services are optional, you can choose to configure Cricket entirely locally. It comes with its own WiFi hotspot, which allows you to configure it either from a phone or a laptop from any web browser.

Cricket empowers you to build fast, ultra-low-power, IoT devices based on WiFi.

Cricket’s Key Features:

• Ultra-low power: 1V – 3.5V (e.g. can run directly on AAA batteries)
• 0.5uA deep sleep
• Battery monitor
• ~3 seconds latency data transmission from a sensor to client devices
• Built-in temperature sensor
• Configurable via the local WiFi captive portal
• Configurable communication protocols: MQTT and HTTP
• Secure connectivity HTTPS
• Configurable 1x Analog and 3x Digital inputs
• Configurable from a FREE remote cloud service cota.thingsonedge.com (optional)
• FREE MQTT cloud service (optional)
• OTA firmware updates

Software integration

Cricket comes with native support of MQTT and HTTP(S) protocols. They allow you to integrate your devices to almost any software and internet service. You can draw some pretty dashboards and present data in real-time from your devices literally in minutes as you do not have to code and program anything.

There is a huge ecosystem of software and services to which you can easily integrate Cricket. To mention a few: Blynk, IFTTT, Zapier, Pushsafer, Home Assistant, Node-RED, Grafana, OpenHAB, Domoticz, Fhem, AdafruitIO, Thingspeak, IoT On/Off, MQTT Terminal, MQTT Dash.

The integration is very powerful as it can make your device for example send email(s), call a phone, log data to Google Spreadsheet, send push notifications, SMS, create a post on social media, you can do anything you like!

What can you do with the Cricket?

Cricket is a “product ready”, designed as a plug-and-play module for making various IoT devices. Devices that can sense, connect and transmit data and events instantaneously from remote locations. Simply attach a battery, add a sensor and your device is ready to go.

There is a wide range of peripherals and sensors which you can attach directly to Cricket such as:

• Temperature sensor [external]
• Light sensor
• Accelerometer / Gyroscope
• Microphone (for noise detection)
• PIR / Motion sensor
• Magnetic switch
• Moisture sensor
• Button

and many more.

This allows you to build various devices, just for example:

• Alarms (fire, smoke, noise, etc.) with phone call notifications
• Motion sensor with phone notifications
• Doorbell (a push button) which rings your phone instead of a chime
• A flower moisture sensor
• HUE light switch
• Meteorological station
• Window / door alarms

You can also attach more advanced circuits and microcontrollers with extra logic and use Cricket to send its data and events.
With Cricket there are endless applications for reporting various data and events from any remote sensory devices.
