What parts does the forehead thermometer consist of?
Infrared Temperature Sensor: The infrared forehead thermometer generally measures temperature at a distance of 1~3cm from the forehead. The collected data is then amplified by the signal amplification circuit and sent to the processor for processing.
MCU Microprocessor: This processes the data transmitted by the infrared temperature sensor. For analog sensors, an A/D conversion circuit is necessary to convert the analog signal into a digital signal, which is then processed by the MCU. For digital temperature sensors, the MCU can directly process the data.
Display Screen: Usually controlled by the MCU to display temperature data.
Button Module: Used for mode switching, allowing users to switch between measuring objects, measuring the forehead, measuring the neck, etc. The buttons can be customized and used as a power button, system reset key, etc.
Buzzer Alarm: This alarm module, by setting the normal temperature range, activates the buzzer when the body temperature exceeds the upper limit or falls below the lower limit, indicating abnormal body temperature.
Crystal Oscillator Circuit: This provides the clock for the MCU microprocessor to ensure oscillation.
Battery: The battery serves as the main power source for the forehead thermometer, making it portable with low power consumption. The system enters sleep mode to achieve lower power consumption and prolong battery life.
Power Management System: Since the power supply voltage of infrared temperature sensors, display screens, buzzers, and other modules may not be the same, the battery needs to be converted into a suitable voltage value for each module. Rechargeable batteries can also be used with the inclusion of a charging circuit.
Secondly, what is the difference between the forehead thermometer with Bluetooth?
Infrared body temperature detectors and forehead thermometers are two commonly used instruments for rapid body temperature measurement. For security inspection in crowded areas, the infrared body temperature monitor is suitable, but its expensive equipment and large size make it impractical for enterprise units. Some enterprise units opt for forehead temperature guns to conduct temperature monitoring of employees.
Conventional forehead thermometers, while providing fast readings and ease of use, require manual registration of data, leading to inefficiency and potential omissions. To address this, forehead thermometers with built-in Bluetooth modules have been introduced. The main functions of Bluetooth forehead thermometers include:
- Measure Body Temperature.
- Realize Cloud Storage of Body Temperature Data: After measuring body temperature, data is automatically uploaded to the cloud for recording and analysis.
- View Daily Temperature Measurement Data Through the Cloud: Data can be exported to electronic files for storage, facilitating record-keeping.
- Generate Temperature Curve Graphs: Enterprises can create temperature curve graphs based on employees’ historical body temperature records, monitoring employees’ physical health.
Forehead thermometers with Bluetooth efficiently transmit body temperature data, making them suitable for comprehensive occasions with huge and difficult-to-manage temperature measurement data. They effectively enhance the efficiency of monitoring an individual’s body temperature, representing a more advanced body temperature measuring instrument.
