A device is provided for detecting residual gas content inside a gas canister and issuing a warning of gas leakage. The device includes at least one temperature sensor, one pressure sensor, a calculation/processing circuit, an alarm element, a display device, and a power supply. The temperature sensor is arranged in a gas regulator or periphery of a gas range to detect temperature of surrounding and issue a temperature signal. The pressure sensor is arranged at a high-pressure side of the gas regulator to detect the gas pressure from a gas canister and to issue a pressure signal. The calculation/processing circuit is connected to the temperature sensor and the pressure sensor to receive the temperature signal and pressure signal for calculating the residual gas content in the gas canister and identifying gas leakage occurring in pipe lines and the gas regulator and issuing an alarm signal in response to the identification of gas leakage. The alarm element and the display device are connected to the calculation/processing circuit to issues warning of leakage and display the residual gas content and the warning of leakage. The power supply provides working power to the temperature sensor, the pressure sensor, the calculation/processing circuit, the alarm element, and the display device.
