Temperature humidity sensor
A small square temperature and humidity sensor whose vent and board-to-board offset decide whether the closed housing still reads true.
Last updated: September 2026
What this product is
A small temperature and humidity sensor is a board behind a vent. Cover that vent with a logo sticker, or snap the housing too tight, and the number drifts because the element cannot breathe. That is the detail worth writing down. Ask whether the radio is Wi-Fi or another link before you plan the app, and ask whether there is a screen or only a phone reading. Those choices change both the quote and the manual. Compare several samples with one reference meter in the same room, then close the cases and compare again. Offsets between boards should be recorded, not averaged into a slogan. Private label here is a face mark and a short insert. A sealed rechargeable pack, or a private dashboard, is outside this platform. The band is an indicative ex-works range for a common square room sensor before freight. Radio rules and the cell are separate. Do not claim laboratory accuracy. The sample set is the evidence you have.

Indicative estimates only. Actual margins vary by supplier, quantity, specifications, shipping, duties, taxes, marketplace fees, advertising and destination market.
Why it is interesting
- Vent placement and board-to-board offset are concrete sample checks on a product that otherwise looks like a plain square.
- Naming the radio up front keeps the app story from being invented after the housings are molded.
What to specify
- Form
- Small square climate sensor
- Measures
- Temperature and relative humidity
- Vent
- Opening checked with the housing closed
- Radio
- Link type confirmed; rules outside the unit estimate
- App
- Factory app on most first orders
Customization and private label
A face logo and a printed insert fit the factory app; a private dashboard, a sealed rechargeable pack, or a radio change is outside this unit band.
Some customization is realistic on this kind of product. Private label packaging is often possible once artwork is approved. Read how private label manufacturing in China is handled, and when a new product needs the OEM/ODM path.
How the desk would source it
- Note 1. Compare several closed housings against one reference meter and write down the spread.
- Note 2. Do not cover the vent with a logo. Placement of the mark is part of the spec.
The usual path is the same as other China factory sourcing: confirm the spec, compare factories, sample, then inspect before shipment. China supplier verification and China quality inspection are available. Goods can be received at the Xiamen warehouse and moved through China warehouse consolidation or sea, air, and express freight.
Questions about this product
Why compare more than one board?
Calibration offset between boards shows up only when several closed housings sit next to the same reference meter.
Is the radio type assumed?
No. Confirm Wi-Fi or another link before the app story is planned. Radio rules are outside the unit estimate.
Do first orders include a private dashboard?
Most first orders use the factory app, not a private app. Destination electrical or battery rules are also outside the unit estimate.
