Grove - mini PIR motion sensor 微型紅外線動作感測器 人體感測模組
Grove - mini PIR motion sensor 微型紅外線動作感測器 用於製作運動檢測應用，例如報警防盜系統，訪客存在監控，燈光開關和機器人。Grove - 迷你PIR運動傳感器是一款緊湊，低功耗，高性價比的PIR傳感器，適用於相對較少檢測距離的應用場合。數據表中的檢測距離可達3米至5米，但是2米是我們推薦的最佳檢測距離，25℃是最適合的溫度。傳感器的靈敏度是可調的，在板的背面有預留的引腳，這樣就可以焊接滑動變阻器來調節靈敏度。如果你覺得靈敏度不夠，這裡有個小竅門，把塑料帽稍微拉一下，有助於提高靈敏度。

 

注意：方向會影響靈敏度，為了更準確的檢測，請將傳感器放置在下圖中。

特徵：

PIR sensor is used for making motion detecting applications such as alarm burglar systems, visitor presence monitoring, light switches and robots. The Grove – mini PIR motion sensor is a compact, low power consumption and cost effective PIR sensor which is suitable for applications with relatively less detection distance requirement. The detection distance in the datasheet is up to 3m to 5m, however 2m is the best detection distance that we recommend and 25℃ is the most suitable temperature.
The sensitivity of the sensor is adjustable, there is reserved pin out on the back of the board so that you can solder a slide rheostat to adjust the sensitivity. If you think the sensitivity is not enough, here is a trick, drag the plastic cap a little up will help enhance the sensitivity. Note:Please note that the orientation can influence the sensitivity, for more accurate detection, please place the sensor as the picture below.
Features:

Low power consumption
Sensitivity adjustable
