在S120中，根据所述第一电压信号，确定耳温枪所在的环境温度。
PCBA主控板根据接收到的第一电压信号，计算所述耳温枪所在的环境温度，并根据环境温度判断是否开启恒温加热模块对温度感测组件进行加热。

其中，所述第一温度阈值为根据人体感受得到的经验值，如28度，PCBA主控板将环境温度与第一温度阈值进行比较，当环境温度大于或等于28度时，则不开启恒温加热模块，可以在不加热耳温枪的情况下，量测人体耳温。
在S140中，当所述环境温度低于所述第一温度阈值时，则控制开启所述恒温加热模块对温度感测组件进行加热。
例如，当环境温度低于28度时，则PCBA主控板控制开启恒温加热模块，使恒温加热模块产生热量，通过热传导实现对耳温枪感测头和红外传感器的加热，使用加热后的耳温枪量测人体耳温。
上述S140可以包括：当所述环境温度低于所述第一温度阈值时，根据第二温度阈值控制所述恒温加热模块对所述温度感测组件进行加热。
其中，所述第二温度阈值可以为经验得到的放到人体耳朵的舒适温度，第二温度阈值可以与上述第一温度阈值相同，也可以与上述第一温度阈值不同，如，将第二温度阈值设置为30度，当环境温度低于所述第一温度阈值时，PCB主控板控制为恒温模块提供电流，发热直至恒温加热模块的温度达到30度。恒温加热模块产生的热量能够通过热传导的方式实现对温度感测组件的加热。
可选地，如图4所示，根据第二温度阈值控制所述恒温加热模块对所述温度感测组件进行加热，可以包括S142-S150。
在S142中，根据所述第二温度阈值控制流入所述恒温加热模块的电流，使所述恒温加热模块对所述温度感测组件进行加热。
其中，可以预先根据实验数据建立第二温度阈值与加热电流的关系表，PCBA主控板根据第二温度阈值，通过查找上述关系表，确定对恒温加热模块施加的供电电流，根据查表得到的电流控制流入所述恒温加热模块的电流。如第二温度阈值设置为38度，通过查找上述关系表得到使恒温加热模块加热到38度对 应的供电电流。
其中，也可以预先建立第二温度阈值与加热电压的关系表，PCBA根据第二温度阈值，通过查表确定对恒温加热模块施加的供电电压，控制恒温加热模块的供电电压，实现对恒温加热模块的加热。不同的第二温度阈值，可以对应不同的供电电流或供电电压。
在S144中，接收所述红外传感器发送的与所述恒温加热模块的实时温度对应的第二电压信号。
在S146中，根据所述第二电压信号，确定所述恒温加热模块的实时温度。
其中，在PCBA控制流入恒温加热模块的供电电流的过程中，可以通过红外传感器监测恒温加热模块的实时温度，并将恒温加热模块的实时温度反馈给PCBA主控板，以使得PCBA主控板对输入恒温加热模块的供电电流进行调整。
在S148中，当所述恒温加热模块的实时温度大于或等于所述第二温度阈值时，停止对所述恒温加热模块通入电流。
其中，PCBA主控板将恒温加热模块的实时温度与第二温度阈值进行对比，当所述恒温加热模块的实时温度大于或等于所述第二温度阈值时，PCBA主控板将可以控制减小恒温加热模块的供电电流，或者控制停止对恒温加热模块进行供电，并继续接收红外传感器反馈的恒温加热模块的实时温度。
在S150中，当所述恒温加热模块的实时温度低于所述第二温度阈值时，继续对所述恒温加热模块通入电流，使所述恒温加热模块对所述温度感测组件继续进行加热。
其中，当所述恒温加热模块的实时温度小于所述第二温度阈值时，PCBA主控板将可以控制增大恒温加热模块的供电电流，或者以原电流继续对恒温加热模块进行供电，并继续接收红外传感器反馈的恒温加热模块的实时温度，直至 恒温加热模块的实时温度达到第二温度阈值。之后可以继续接收红外传感器反馈的恒温加热模块的实时温度，对恒温加热模块进行持续监测，并调整恒温加热模块的供电电流，也可以调整恒温加热模块的供电电压。
通过红外传感器实时监测并反馈恒温加热模块的温度，使得PCBA能够及时调整恒温加热模块的供电电流或供电电压，使恒温加热模块维持在第二温度阈值，实现恒温加热。
可选地，当所述恒温加热模块的实时温度大于或等于所述第二温度阈值时，还包括：发送第一提示信息，其中，所示第一提示信息为语音提示、指示灯提示和文字提示中的至少一种提示信息。

在S210中，获取环境光传感器发送的实时电流信号。
其中，环境光传感器可以感知周围环境的光线强度，当耳温枪放置的位置发生改变时，环境光传感器检测到的周围环境的光线强度发生改变，环境光传感器输出的电流信号，如电流值，也会产生变化。
环境光传感器可以监测周围环境中的光线强度，本实施例中环境光传感器可以采用光线强度越强，输出电流越小，采用光线强度越弱，输出电流越大的传感器。
环境光传感器输出至PCBA的实时电流能够反映出耳温枪与人耳的距离，在将耳温枪移动至人体耳部的过程中，越接近人耳，光线被遮挡的部分越多，环境光传感器检测到的光线强度越弱，电流逐渐增大，环境光传感器将实时检测周围环境的光线强度，并输出对应的实时电流信号。
在S220中，将所述实时电流信号与预设电流阈值进行对比。
其中，预设电流阈值可以为实验测得的电流数据，如对耳温枪的摆放位置进行实验，将耳温枪的感测头正确插入人耳情况下，环境光传感器输出的电流信号作为预设电流阈值，预设电流阈值可以为一电流值范围，也可以为一个具体电流值，可以将实时电流信号的电流值与预设电流值进行对比，根据对比结果，确定所述耳温枪是否摆放正确。
在S230中，当所述实时电流信号未达到预设电流阈值时，不获取红外传感器发送的第三电压信号。
在S240中，当所述实时电流信号达到预设电流阈值时，获取红外传感器发送的所述第三电压信号，并根据所述第三电压信号计算人体耳温。
其中，第三电压信号为耳温枪的红外传感器收集人体耳道内的红外辐射能量转换得到的电压信号，预设电流阈值可以为预设的电流阈值范围，PCBA主控板可以将环境光传感器输出的实时电流值与预设电流阈值范围进行比较，当所述实时电流值不在预设的电流阈值范围内时，则确定耳温枪摆放错误，PCBA主控板不获取红外传感器发送的第三电压信号；当所述实时电流差值在预设的电流阈值范围内时，则确定耳温枪摆放正确，PCBA主控板获取红外传感器发送的第三电压信号，计算人体耳温。
PCBA主控板可以将接收到第三电压信号的电压值与环境温度对应的红外传感器输出电压值进行差值计算，得到电压差值，根据电压差值得到人耳温度。 例如环境温度为25度时，红外传感器输出的电压值为1mV，对被测者进行耳温量测时，红外传感器输出的的电压值为13mV，电压差值为12mV，若电压相差1mV，温度相差1度，则可得被测者的耳温为37度。
可选地，当所述实时电流信号未达到预设电流阈值时，还包括：发送第二提示信息，其中，所述第二提示信息为语音提示、指示灯提示和文字提示中的至少一种提示信息。
其中，通过发送提示信息可以对用户进行提醒，如耳在温枪上设置指示灯，当当所述摆放距离未达到预设距离阈值时，指示灯可以由红色变为绿色，或者在耳温枪上设置语音模块，播放提示音，如播放“位置正确，开始量测”的语音提示，或者在耳温枪上设置显示屏幕，并显示“位置正确，开始量测”的文字提示信息。
测耳温时，耳温枪的摆放位置对耳温的量测结果有较大影响，通常存在使用者操作不当，将耳温枪放置在错误的量测位置，如将耳温枪放在耳朵边上进行耳温量测，使得量测的耳温不准，本实施例中，在耳温枪上设置环境光传感器，通过检测环境中的光线强度，判断是否将耳温枪放入正确的人耳量测位置，确保耳温量测的有效性，提高耳温量测结果的准确性，在耳温枪摆放错误的情况下不获取红外传感器的量测信号进行后续计算，还可以减少部分功耗，对放对位置是否正确进行提示，可以及时对用户进行提醒，便于用户矫正量测姿势，提升用户体验。
