temperature_sensor_reader
This is a temperature sensor package designed for modbus. Implemented in pymodbus only. PyPI website: https://pypi.org/project/temperature-sensor-reader-xzf8971/
Install
from pypi:
pip install temperature-sensor-reader-xzf8971 from github:
pip install git+https://github.com/xzf89718/temperature_sensor_reader
Jiandarenke modbus RS485 as example
Before run scripts
Check the COM and chmod
chmod 666 \dev\ttyUSBxImport modules
from modbus_configuretools import temperature_sensor.RS485_Jiandarenke as RS485_JDRK
from modbus_configuretools import temperature_sensor.JDRKAddressConfig as ConfigConfigure parameters for Jiandarenke RS485 sensor
It's OK to set None for unkown value
# Modify these config values
# Please configure these value in temperature_sensor before read or write values
# SLAVEID must be specified. If SLAVEID is none, set to 1

sensor.CalibrationJiandarenke(myconfig) Set slaveID and baudrate
Please make sure only 1 sensor connect to the modbus bus
sensor.WriteSlaveIDAndBaudrate(myconfig)Init and read measured values from sensor
# Create a wrapper for JDRK sensor
sensor = RS485_JDRK(port="/dev/ttyUSB0")
# Init and connect client
sensor.InitClient()
# Read slaveID and baudrate
slaveID, baudrate = sensor.ReadSalveIDAndBaudrate(myconfig)
# Read temperature, dew point, humidity in one request
# Only correct for specified sensor
temperature, dew_point_temperature, humidity = sensor.ReadTemperatureAndHumidity(myconfig)
# Read temperature only
temperature = sensor.ReadTemperature(myconfig)
# Read dew point temperature
dew_point_temperature = sensor.ReadTemperatureDewPoint(myconfig)
# Read humidity only
humidity = sensor.ReadTemperature(myconfig) Close the sensor
sensor.close()
