In the Neonatal Intensive Care Unit (NICU), every infant incubator is a guardian station for fragile lives. Premature and low-birthweight infants receive precise constant-temperature and constant-humidity care here, and the absolute safety of the equipment is the first line of defense. Today, we ...
Landslides, collapses, and debris flows threaten lives, property, and major projects year-round. Harsh outdoor environments make geological monitoring challenging—extreme weather, dust, complex terrain movement, and the need for 24/7 unattended reliability demand more than traditional methods can...
1. Application Introduction A motor is an electromagnetic device that converts electrical energy into mechanical energy and vice versa. Motors generally have two applications: the first is to convert mechanical energy into electrical energy, known as a generator; the second is to convert electric...

We have an iPhone app available, but not for Mac yet. We also don't have a tutorial for connecting the product to the app yet, but we will be developing one later.

App download: iPhone App Store

Our attitude sensors are all inertial sensors. The angles expressed in the product are in the internally rotated Euler angle coordinate system. The Euler angle order is the same as the ZYX order.
The Bluetooth module has an autoConnection property, which cannot be turned on. Check whether automatic connection is enabled.
The order of Euler angle rotations is: zyx, internal rotation; the order of quaternions, q0, q1, q2, q3, corresponds to w, x, y, z.

Thanks! It's quite simple to use thanks to your manuals. I had some trouble connecting to arduino and mail to witmotion. They were very kind and quick to reply. So I was able to solve the problem in a day. It is very reasonable price and easy to use.

This is how hardware and software should work in 2024

Due to an Android update I had a problem with recording the data at first. But Customer Support was able to solve this for me quickly though WhatsApp.
The sensors start instantly when turn on and then immediately connect to your Phone.
Then I get nice reading of the sensor values on my Phone. I need to do more testing to see if the product is suitable for my needs, but I'm very pleased so far.
