SPECIFICATIONS

A: Yes. The USB-UART serial converter would be required.

Q: If I run into any issue when use the sensors? Can you help?

A: Certainly, if you have any questions, WitMotion technical support team will be here to help.

You can reach us at support@wit-motion.com, Normally response time: 12Hrs

Q: What is the difference between HWT901B standard version and HWT901B waterproof version?

A: Except for the acceleration, gyro, angle, and magnetic data, the HWT901B standard version will be equipped with barometer which can output the air pressure, height data. But it is not waterproof.

However, the HWT901B waterproof version will not be equipped with barometer. (*due to glue-pouring process)

Q: I need the sensors with a longer cable, printed with our logo (OEM order) or customized functions, can you make it?

A: The answer is YES. The sensor order with customization requests would be welcome.

* We can produce the sensors with cable as TTL (1 meter), RS232 (10 meters maximum), RS485 (100 meters).

* OEM logo with customer's logo would be available. Once you share the LOGO.ai file, our photographer will help you finish the * design.

* There are over 25+ professional engineers ready for helping you build the preferred sensor.

* If you need 20pcs or above large quantities, pls directly contact us.

Q: Can I use the HWT901B or HWT905 sensor for iOS?

A: Nope. Due to the communication protocol and port design, WitMotion serial sensors are not compatible with iOS operating systems by now.

But you can search WitMotion WT901BLECL on our store, for which it can work well with iPhone.

Q: If I plan to use the sensors for Arduino, or Raspberry Pi, which one is recommended?

A: Considering the Arduino and Raspberry Pi is commonly in TTL level, the HWT901B with TTL interface would be highly recommended.

If you are able to make the hardware changes from RS232/RS485 - TTL and then connect it with your boards, each one would be suggested.

Q: I plan to use the HWT901B sensor with my Android smartphone, do I need to purchase additional tools?

A: All tools are sold separately. A USB Type-C/Micro USB to USB adapter is used to demonstrate connection to a PC or mobile phone. You can consult and buy if necessary.

Q: I am new about the attitude sensors, shall I buy any other tool for the connection?

There will be a manual with step by step guiding to set up the sensors.

A:  You can scan below QR code and visit the witmotion document center link and search the model you bought.

Q: Where can I find the tutorial and related software for the sensors?
