便捷式電子儀器,使用率最高的額溫槍(紅外線測溫儀),1秒可準(zhǔn)確測溫,無鐳射點(diǎn),免除對眼睛之潛在傷害,不需接觸人體皮膚,避免交叉感染。為我們快速控制疫情,起著非常大的重要作用,在疫情早期,紅外線測溫儀一度供不應(yīng)求,可想而知它的需求量有多大。
紅外測溫槍針對測量人體額溫基準(zhǔn)設(shè)計(jì),實(shí)現(xiàn)非接觸式測溫之目的,操作簡單方便。1秒可準(zhǔn)確測溫,有效降低人與人之間的交叉感染之隱患。晶振的作用是為MCU提供基準(zhǔn)時(shí)鐘信號,以確保MCU各項(xiàng)指令順利進(jìn)行并完成,
晶振在實(shí)際工作中若出現(xiàn)不穩(wěn)定,如頻偏過大或不起振,會直接造成MCU失去指令功能,不良現(xiàn)象表現(xiàn)為不開機(jī)、LCD顯示屏無法點(diǎn)亮、或測溫遲緩等問題。
紅外測溫槍為便攜式電子儀器,需要電池供電,因此對晶振存在低功耗需求,晶振選型多為貼片式、小體積、低功耗??傊д窆ぷ髟椒€(wěn)定且精度越高,紅外測溫槍測溫反應(yīng)越快,越精準(zhǔn)。
