This is not your normal PIR! The Qwiic Human Presence Sensor - AK9750 is a passive infrared sensor with four discrete sensors built into one digital package. PIRs are most often used in security systems to detect the movement of a human walking through the room. If you’ve ever seen a 1" white sphere in the corner of a room, that’s a PIR. We sell a simple PIR as well but the AK9750 is far more advanced. The AK9750 is a digital sensor giving you a 16-bit digital value over I2C. Furthermore, the AK9750 has four sensors built in! This allows you to detect not only presence but relative distance and direction of movement (for example: PIR2 went off then PIR4 went off so the human is moving left to right).
Each of the four sensors outputs the IR current in pico-amps (-14,286 to 14,286pA). A PIR reading can vary from roughly -200 (no human present) to 1500 when a human is detected standing in front of a given channel but it varies due to environmental factors and other heat sources in view. We’ve written a library to control the sensor and included a examples showing how to output the sensor readings. We’ve also written a Processing sketch to visualize the IR sensor readings in real time.
The Qwiic Human Presence Sensor - AK9750 is rear mounted through the 0.8mm thick PCB. Additionally, the sensor ships without a lens. We’ve found the sensor to perform quite well and detect human movement over 10 feet (3 meters) away without the standard Fresnel lens.
Need many eyes in the sky? The ADR jumpers allow up to 3 sensors on a bus. Need more? Our Qwiic Mux will enable up to 192 sensors for a total of 768 presence readings. Eeek!
This board includes Qwiic connectors. The Qwiic system enables fast and solderless connection between popular platforms and various sensors and actuators. You can read more about the Qwiic system here.
We do not plan to regularly produce SparkX products so get them while they’re hot!

這是不是你的正常PIR！所述Qwiic人體存在傳感器 - AK9750是與內置到一個數字化包四個離散傳感器的無源紅外傳感器。執行報告是最經常在安全系統中使用過的房間，以檢測人說話的運動。如果你見過在一個房間的角落1“的白色球體，這是一個PIR。我們賣一個簡單PIR以及但是AK9750是更先進。該AK9750是一個數字傳感器給你一個16位數字值超過I 2。此外，以AK9750已建成四個傳感器這可以讓你不僅檢測存在，但相對距離和運動方向（例如：PIR2去了那麼PIR4去了所以人是從左向右移動）。
每四個傳感器的輸出在微微安培的電流IR（-14,286至14,286pA）。檢測到人時站立在給定信道的前一閱讀PIR可以從大約-200（沒有人類存在）至1500有所不同，但它改變由於環境因素和考慮其它熱源。我們已經寫了一個庫來控制傳感器和包括一個例子來說明如何輸出的傳感器讀數。我們還寫了一個處理草圖可視化實時紅外傳感器讀數。
所述Qwiic人體存在傳感器 - AK9750是後置通過0.8mm厚的PCB。另外，傳感器一般沒有透鏡。我們發現進行得很順利，檢測超過10英尺（3米）遠沒有標準的菲涅爾透鏡人體運動傳感器。
需要在天空中眾多目光？在ADR跳線允許多達一個總線上的3個傳感器。需要更多？我們Qwiic多路復用器可提供高達192的傳感器，共768存在讀數。 Eeek！
此板包括Qwiic連接器。所述Qwiic系統使流行的平台和各種傳感器和致動器之間的快速和無焊連接。你可以閱讀更多有關Qwiic系統在這裡 。
我們不打算經常產生SparkX產品因此得到他們，而他們是熱的！
