Temperature (DS18S20) component

A rugged temperature sensor allowing one or more sensors to be addressed and read. Capable of reading temperatures from -55 to +125 degrees C. Requires a One Wire component to perform the bus operations.

Examples

This example shows how to connect the DS18S20 component to the OneWire component and either select a specific device on the bus or scan through the devices on the bus collecting the temperature readings.

The temperature and serial number is output using a UART connection as is onboard a Arduino or ESP32 device.

Example DS18S20

Downloadable macro reference

	SampleAllDevices
Performs a temperature conversion on all compatible devices. The temperature can be read using the ReadTemperature macro. Brefore calling ReadTemperature you need to use one of the Address macros.
[[File:]] -	WaitForCompletion
0=Dont Wait, 1=Block and Wait To Complete
- VOID	Return

	AddressSpecificDevice
Starts a temperature conversion on a specific device using a hex string identifier. SerialNumber parameter should be 12 characters and contain the 48-bit Serial.
- STRING	SerialNumber
48-bit Serial Number e.g. "32DF4A3C1901"
- VOID	Return

	GetSerialString
Gets the Serial String for the current addressed device.
- STRING	Return

	AddressNextDevice
Scans for the next connected device with a matching family code. Goes through the device list generated by the ScanBus macro.
- VOID	Return

	GetTemperature
Reads the temperature from the last sample on the selected device. The selected device is set using the AddressNext or AddressSpecific macros.
[[File:]] -	Return

	SampleAddressedDevice
Performs a temperature conversion on the current addressed device. Requires one of the Address component macros to be called. The temperature can be read using the ReadTemperature macro.
[[File:]] -	WaitForCompletion
0=Dont Wait, 1=Block and Wait To Complete
- VOID	Return

	Initialise
Configures each matching sensor on the bus with the specified conversion bits.
- VOID	Return

	Properties
	One Wire Component
Link to the one wire component to host the bus.
	Alarm High
The high byte of the alarm range
	Alarm Low
The Low byte of the Alarm range
	Conversion Bits
The number of bits used to perform a temperature sample. Controls the conversion time and the resolution.
	Max Conversion Time
The maximum amount of time in milliseconds it will take for a sample to complete.
	Temperature Resolution
The maximum resolution steps that the temperature can be read in.
	Number Sensors
