一、產品規格書
Description
The TH02 is a digital relative humidity and temperature sensor. This monolithic CMOS IC integrates temperature and humidity sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C host interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of a low-power, monolithic CMOS sensor IC with low drift and hysteresis and excellent long term stability.
Both the temperature and humidity sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. This ensures that the sensors are fully interchangeable, with no recalibration or software changes required.

四、成功案例,物聯網無線解決方案
在無線防盜和報警系統、無線傳感器、家居自動化遙控、無線高速數據采集系統、無線玩具、溫濕度控制系統、儀器儀表、氣壓測量和控制系統、移動海拔測試、多功能運動表、天氣預報等領域受到日益廣泛的歡迎
2、智能安防報警系統
智能安防報警系統需采用智能網絡專用協議傳輸,總線式通訊,以最簡潔的系統架構,便于設計、施工、使用和管理維護。報警控制主機有多防區機型可供選擇,足以滿足家庭、商業網點、大樓、小區等各種場所的防盜報警需要。電話報警,易于聯網,報警控制主機可通過聯網方式報警,更多的是采用電話網絡報警至保安中心,無需另敷聯網線路,極為方便。采用總線方式布線,可以大大降低系統造價。保安中心通過監控管理軟件實時監測各種系統狀態,可以對報警系統進行雙向控制,還可以與公安局報警中心聯網并自動報警,構成多級聯網報警系統。
3、汽車防盜RKE/PKE設計
1. 整合控制器一體,不怕剪線,汽車級防盜(除非肢解整臺車)
2. 采用跳碼控制,有效防止復制和破解
3. 采用身份識別機制,不用遙控器,走近電動車即無線驗證身份
4. 可實現多種實用功能:聲光尋車、免鑰匙駕駛、遙控停車、被動防盜、行車防搶等等
功能解釋:
1. 免鑰匙駕駛:遙控器與防盜器之間有握手協議,識別成功情況下,可實現免插鑰匙啟動車輛。
2. 行車防搶:行車過程中,遙控器與防盜器之間保持握手,如果握手失敗(有盜賊強行搶車),在規定時間內進行提示,然后進行鎖定電機,不能行駛。
3. 被動防盜:車主駕駛結束后離開(遙控器離開)到一定范圍,防盜器自動進入防盜狀態。
