2 axis Digital High Precision Inclinometer with RS232 modbus
INC829 is high-accuracy and wide measurement range inclinometers
designed by SKYMEMS. Compared to electrolytic or capacitive tilt
sensors, this series products works far better in non-linearity,
repeatability, delay, temperature displacement, operating
temperature, impact-resistance, and vibration-resistance, etc.
As an ultra-high-accuracy inclinometer, INC829 integrates a 24-bit
high-end ARM system with resolution of 0.001°, accuracy of 0.008°,
temperature of 0.0007°/℃, and response frequency as high as 100HZ
(the baud rate is 115200). INC829 is the most competitive product
in the industry.

What is a CAN protocol?
The CAN bus protocol is defined by the ISO 11898-1 standard and can
be summarized like this: The physical layer uses differential
transmission on a twisted pair wire. A non-destructive bit-wise
arbitration is used to control access to the bus.
CAN is a multi-master serial bus standard for connecting Electronic
Control Units [ECUs] also known as nodes. Two or more nodes are
required on the CAN network to communicate. The complexity of the
node can range from a simple I/O device up to an embedded computer
with a CAN interface and sophisticated software. The node may also
be a gateway allowing a standard computer to communicate over a USB
or Ethernet port to the devices on a CAN network.
All nodes are connected to each other through a two wire bus. The
wires are 120 Ω nominal twisted pair.
ISO 11898-2, also called high speed CAN, uses a linear bus
terminated at each end with 120 Ω resistors.
What is Modbus Protocol?
Modbus is a serial communications protocol originally published by
Modicon (now Schneider Electric) in 1979 for use with its
programmable logic controllers (PLCs). Simple and robust, it has
since become a de facto standard communication protocol and is now
a commonly available means of connecting industrial electronic
devices. The main reasons for the use of Modbus in the industrial
- developed with industrial applications in mind,
- openly published and royalty-free,
- easy to deploy and maintain,
- moves raw bits or words without placing many restrictions on
Modbus enables communication among many devices connected to the
same network, for example, a system that measures temperature and
humidity and communicates the results to a computer. Modbus is
often used to connect a supervisory computer with a remote terminal
unit (RTU) in supervisory control and data acquisition (SCADA)
systems. Many of the data types are named from its use in driving
relays: a single-bit physical output is called a coil, and a
single-bit physical input is called a discrete input or a contact.
