描述

我們知道，世界正在經(jīng)歷大流行浪潮。一旦鎖定打開下一波周期性的到來?？谡?，社會距離，消毒，疫苗接種這些是解決這個(gè)問題的主要解決方案。一旦解鎖國家，人們將走出去滿足他們無法停止的需求。人們會去公共辦公室滿足他們的需要。人們必須去商店購買。甚至他們也必須使用自己辦公樓的廁所。人們會逐漸減少預(yù)防措施。即使消毒劑在他們面前，他們也會跳過手部消毒。

現(xiàn)有的解決方案是采取預(yù)防措施的海報(bào)和標(biāo)牌。每個(gè)人都知道，為了防止covid傳播，口罩、消毒、社交距離是解決方案。但隨著時(shí)間的推移，人們會減少預(yù)防措施。他們不會正確戴上口罩，他們會猶豫消毒即使消毒劑在前面。造成這種情況的主要原因是人們只會認(rèn)為（即使他們知道這是錯(cuò)誤的）我不會被感染，電暈已經(jīng)消失，就像那樣。解決方案是每次都向他們展示真實(shí)數(shù)據(jù)，我提出了一種設(shè)備，它可以像現(xiàn)有自動化系統(tǒng)的附加組件一樣。設(shè)備將提供有關(guān)特定空間以及國家和地方 covid 更新的信息，實(shí)時(shí)數(shù)據(jù)將鼓勵(lì)人們采取預(yù)防措施而不會失敗。

用于 aws IoT EduKit 的 core2 將用于制作一個(gè)設(shè)備，該設(shè)備將成為其他設(shè)備網(wǎng)絡(luò)的一部分，并將顯示實(shí)時(shí)數(shù)據(jù)，例如 1. 在新人進(jìn)入“您是今天使用此設(shè)施的第 XXX 個(gè)人。請保持手部消毒并戴上你的面具”可以從另一個(gè)連接的計(jì)數(shù)設(shè)備/門傳感器等中獲取計(jì)數(shù) 2.設(shè)備將顯示國家/地區(qū)的 covid 統(tǒng)計(jì)數(shù)據(jù)（每日病例、病例總數(shù)、死亡人數(shù)等），這將鼓勵(lì)訪客認(rèn)真采取預(yù)防措施. 3.如果設(shè)備在商店店主可以設(shè)置自定義消息和顯示除了covid更新4.設(shè)備將報(bào)警如果任何高溫人員進(jìn)入設(shè)施。數(shù)據(jù)將來自連接的人員溫度監(jiān)視器入口。

訪客體溫讀數(shù)模塊

這個(gè)模塊/設(shè)備將幫助商店/建筑物/空間監(jiān)測訪客的溫度?，F(xiàn)在我已經(jīng)使用粒子光子和溫度傳感器完成了這項(xiàng)工作。

為此，我們需要開發(fā)一個(gè)代碼來讀取溫度并將警報(bào)消息發(fā)送到 aws iot core mqtt 主題，該主題將由我們的 m5 堆棧核心 2 訂閱。
