The HTU21D is a new digital Humidity Sensor with temperature output. Setting new standards in terms of size and intelligence. This sensor provides calibrated, linearized signals in digital, I�C format. The digital humidity sensor is dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a microcontroller is made possible with the module for humidity and temperature digital outputs. These low power sensor is designed for high volume and cost sensitive applications with tight space constraints. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip which can be read out by command. Low battery can be detected and a checksum improves communication reliability. The resolution of these digital humidity sensors can be changed by command (8/12-bit up to 12/14-bit for RH/T).
- Full Interchange-ability with No Calibration Required in Standard Conditions
- Instantaneous De-saturation After Long Periods in Saturation Phase
- Compatible with Automatized Assembly Processes, Including Pb-free and Reflow Processes
- Individual Marking for Compliance to Stringent Traceability Requirements
Applications
Automotive, Consumer Electronics, Computers & Computer Peripherals, HVAC, Industrial
Warnings
ESD sensitive device, take proper precaution while handling the device.

Surprisingly Effective and Convenient!
Color: Bag Petrol
I wasn’t sure what to expect with the purse clean ball, but it has turned out to be a great little gadget! It’s simple to use—just toss it into your purse, and it quietly works to pick up crumbs, lint, and small debris.
The sticky interior does an excellent job of collecting all the random dirt that accumulates, and it’s easy to clean—just rinse it under water, let it dry, and it’s good as new. I also love that it’s compact and doesn’t take up much space in my bag.
If you want an easy way to keep your purse tidy without constantly emptying and shaking it out, this is a fun and effective solution. Highly recommend it for anyone who likes to keep their bags neat and clean!

Highly recommend
Color: Black
I love these so much. They make the perfect stocking stuffer but as a chronically messy person, I love throwing them in my purse or backpack. They pick up so much and are really easy to wash off.

Clean Your Purse
Color: Pink
This ball is pretty cool. It acts like a lint roller inside your purse getting all the dirt, crumbs, & lint that accumulates at the bottom. When it's looking nasty, you can rinse it off in the sink & it's good to go back in your purse. It's one of my best Amazon purchases and I will probably buy again if/when the sticky wears off or having a spare on hand.

Value for money
Color: Blue
This definitely is something to have. Used it a lot while travelling and for office use as well. It takes out all the gunk from the bag and is easy to clean as well
