Sensor Configuration

Sensors are configured using the ‘J’-command. The J command is followed by a configuration
string consisting of excactly 100 binary values describing all sensors and parameters. The
order of sensors are not important, as long as the configuration starts at the first position and
is immediately followed by the next configuration.0

A configuration string is built as shown in the following figure:

Sensor 1

Sensor 2

Sensor…….

Sensor N

0x00

…0x00

Example configuration

The following array of bytes (in hexadecimal representation here) configures the analog
sensor and the SHT35 sensor:

0x0B 0x01 0x01 0x0E 0x10 0x00 0x00 0x00 0x00 0x00
0x00

0x0B 0x03 0x01 0x1C 0x20 0x00 0x00 0x00 0x00

0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00

Description of example:



First sensor to be configured is the analog sensor in

BLACK



Length of sensor configuration is set to 0x0B, which is the length of the analog sensor
configuration



Type is set to 0x01 (Analog sensor)



Version is set to 0x01



Period is set to 1 hour (0x0E10 =3600 seconds)



6 bytes of 0x00 is sent to fill in the not-used fields



Second sensor to be configured are the Sensirion SHT35 in

GREEN



Length of next sensor configuration is set to 0x0B, which is the length of the SHT35
sensor configuration



Type is set to 0x03 (SHT35)



Version is set to 0x01



Period is set to 2 hours (0x1C20 =7200 seconds)



6 bytes of 0x00 is sent to fill in the not-used fields



The last 0x00s in

RED

is padding at the end of the configuration array, as the array

must be a total of 100 bytes.

To send and enable the configuration, the following sequence is used:

1. Enter config mode either by sending 0x00 on UART or enabling the CONFIG pin on

the module

2. Send character

J

3. Wait for prompt (

>)

4. Send the 100 bytes of configuration data on the UART
5. Wait for prompt (

>

)

6. (Do other configuration operations)
