Reference Design for a high-end gas cooker

Reference design for a high-end gas stove that can improve the safety and convenience of the user.

Gas stoves are one of the most essential commodities and is found in almost all the houses. But a device throwing flames should have some safety features to protect the user, moreover, the in-efficient burning of gas may result in toxic emission and higher gas cost.
So, to enhance the efficiency of the gas stove and to improve the safety, Renesas has released a high-end gas stove that features a micro-switch which can ignite the gas. The high-end gas stove uses a 9V battery as power supply. The reference design is based on RL78/G11 MCU and features a few LEDs and buzzer to alert the users in case of any abnormality. The reference design also offers flame temperature detection circuit that starts to detect the voltage signal of thermocouple feedback. Then it will judge whether the ignition is successful by voltage signal. If the ignition is successful, it will continue to detect flame temperature; but if the ignition fails, the alarm will be turned on to alert people.

The high-end gas cooker’s gas detection circuit can detect the concentration of natural gas and when the concentration exceeds the standard then it can automatically disable ignition and close the electromagnetic valve and give an alarm tone. It also features an anti-dry protection device that can avoid occurrence of danger and waste of gas effectively.

This reference design has been tested by TI. It comes with comprehensive software, firmware libraries, tools, battery, etc. You can find additional data about the reference design on the company’s website. To read more about this reference design click here.
