Smart BBQ Thermometer

BBQ enthusiasts and home cooks value precision in cooking, especially for meats. A smart, connected thermometer allows users to monitor cooking temperatures in real time without hovering over the grill. Alerts are sent to a device, such as a smartphone, when target temperatures are reached, reducing the risk of overcooking or undercooking and enhancing food safety.

This BBQ thermometer design elevates the cooking experience by enabling smart connectivity via a Wi-Fi and Bluetooth^® Low Energy (LE) module or Bluetooth LE SoC, allowing the thermometer to connect to a smartphone and send alerts when optimal cooking temperatures are reached. The system consists of a base station and a sensor probe (placed or inserted into the product being cooked) that communicates wirelessly, enhancing overall safety and user experience. To maximize durability and safety, the temperature probe is completely sealed (with no connectors) and is wirelessly recharged using NFC wireless charging when placed on the base station. The base station can either be connected to a power supply or charged wirelessly via NFC technology, using Renesas' universal NFC wireless charger.

Our alternative design features a wired connection between the base and the sensor while still retaining the smart connectivity and communication interface to send alerts to a phone app.

System Benefits:

• Real-time temperature monitoring to track and visualize cooking temperature enables precise control and perfectly cooked dishes every time.
• Fully sealed and durable wireless design for power and communication provides a safer and more streamlined cooking experience.
• Low-power Wi-Fi and Bluetooth LE modules offer longer battery life and low power consumption in a convenient form factor to extend operation and use time between charges.
  • Globally recognized certifications for safety and reliability by the FCC, IC, CE, and others reduce development time and enhance time to market.
