Plantower
Plantower (Nanchang Plantower Technology Co., Ltd.) is a Chinese company that develops, manufactures, and sells air-quality sensors. Its website states that the company was founded in Beijing in 2014 and moved to Nanchang, Jiangxi, in 2018, and that its Plantower-series sensors are used in air-quality monitoring, environmental monitoring, automotive electronics, and smart-home applications.
Product lines
The product section of the official website lists:
- Laser particle sensors: the PMS series, with model numbers including PMS1003, PMS3003, PMS5003, PMS6003, PMS7003, PMS9003M, and PMSA003. The PMS series are low-cost laser PM2.5/PM10 sensor modules; the air-quality sensor research page of the World Air Quality Index project lists them among the representative products in this class.
- Other air sensors: infrared dust sensors, formaldehyde sensors, carbon-dioxide sensors (DS-CO2-20, DS-CO2-30), multi-in-one gas sensor modules, and automotive sensors.
Sensor model numbers, parameters, and selection guides should be read from plantower.com. In the hardware-tinkering community, PMS-series sensors are often paired with microcontrollers such as ESP32 in DIY air-quality monitors.
Discussion in the show
In Weekly #005’s chapter “小硬件成为 Personal Agent 的物理外挂” (small hardware as the physical peripheral of personal agents), Yang Pan mentions that his home carbon-dioxide detector uses a sensor from the “Plantower” brand (paragraph in the Chinese transcript), before moving on to hardware founders pivoting to build physical peripherals for big-platform personal agents. This is the host’s offhand identification of the brand in his own device; Plantower’s official product line covers both particle and carbon-dioxide sensors.
