<p>An in-built temperature monitor 1 for remote temperature monitoring is provided. The temperature monitor is incorporated into a device such as a motor vehicle and includes a display screen 4 and at least one user-operable key or switch 2. A communication unit 10, typically in the form of a mobile telephone module or modem, is provided for transmitting and receiving signals. A temperature sensor 8 measures temperature. A processor unit 6 is programmable with an upper temperature setpoint and a lower temperature setpoint and these are stored in the processor unit and compared against the measured temperature. The processor unit controls the communication unit 10 to transmit an alarm signal to a mobile telephone or other portable electronic device 12 if the measured temperature is above the upper temperature setpoint or below the lower temperature setpoint. The processor unit 6 also controls the communication unit 10 to transmit a status signal when the communication unit receives a demand signal, typically from a mobile telephone or other portable electronic device 12.</p> |
