modbus-configuretools-xzf8971 1.0.0

A package to read/write registers on a temperature sensor with python.

temperature_sensor_reader

This is a temperature sensor package designed for modbus. Implemented in pymodbus only.

Jiandarenke modbus RS485 as example

Import modules

from modbus_configuretools import temperature_sensor.RS485_Jiandarenke as RS485_JDRK
from modbus_configuretools import temperature_sensor.JDRKAddressConfig as Config

Configure parameters for Jiandarenke RS485 sensor

# Modify these config values # Please configure these value in temperature_sensor before read or write values
# ADDRESS_HUMIDITY = 0x0000
# ADDRESS_TEMPERATURE_DEW_POINT = 0x0001
# ADDRESS_TEMPERATURE = 0x0002
# ADDRESS_TEMPERATURE_CALI = 0x0050
# ADDRESS_HUMUDITY_CALI = 0x0051
# ADDRESS_SLAVEID = 0x07D0
# ADDRESS_BAUDRATE = 0x07D1
# TEMPERATURE_CALI = 164
# HUMIDITY_CALI = 7
myconfig = Config(ADDRESS_HUMIDITY, ADDRESS_TEMPERATURE_DEW_POINT, ADDRESS_TEMPERATURE, ADDRESS_SLAVEID, ADDRESS_BAUDRATE, ADDRESS_TEMPERATURE_CALI, ADDRESS_HUMUDITY_CALI, TEMPERATURE_CALI, HUMIDITY_CALI)

Calibration of sensor. Not necessary calibration every time

sensor.CalibrationJiandarenke(sensor.cfg.ADDRESS_TEMPERATURE_CALI, sensor.cfg.ADDRESS_HUMUDITY_CALI, slaveID=1)

Init and read registers from sensor

# Create a wrapper for JDRK sensor
sensor = RS485_JDRK(port="/dev/ttyUSB0", myconfig)
# Init and connect client sensor.InitClient()
# Read slaveID and baudrate
slaveID, baudrate = sensor.ReadSalveIDAndBaudrate(salveID=1)
# Read temperature, dew point, humidity in one request
# Only correct for specified sensor temperature, dew_point_temperature, humidity = sensor.ReadTemperatureAndHumidity(slaveID=1)
# Read temperature only
temperature = sensor.ReadTemperature(slaveID=1)
# Read dew point temperature
dew_point_temperature = sensor.ReadTemperatureDewPoint(SlaveID=1)
# Read humidity only
humidity = sensor.ReadTemperature(slaveID=1)

Close the sensor

sensor.close()
