ขาย Francesco เซนเซอร์ตรวจจับก๊าซคาร์บอนไดออกไซด์ทนทานสําหรับ Arduino Co2 Eco2 Tvoc 3.3V Ccs811 ราคาที่ดีที่สุด

<div><p>Package contains: 1 x CCS811 sensor module Module size: 15mm x 21mm Resolution: 14-bit resolution Power supply: 3.3V Sleep mode current: 100nA CCS811 is a gas sensor chip system chip (SSoC) + temperature and humidity sensor, which uses low-power sensing technology to detect indoor volatile organic compounds (VOC). CCS811 has an integrated MCU, the sensor has on-board processing capability, without host intervention, can provide equivalent levels of carbon dioxide or total volatile organic compound (TVOC) index. At the same time, by using a separate gas sensor and MCU solution, CCS811 can save equipment inventory costs and save up to 60% of the total board area. The relative humidity is 2% (typical value). The temperature accuracy is + 0.2 C (typical value).</p></div>
