Tip

This library has its own demo,click this link to view onewire demo examples

Example

-- This code base is still under development

onewire.ds18b20(mode, pin, check)

Read DS18B20

Parameters

Incoming Value Type	Explanation
int	GPIO The mode corresponds to the GPIO number, and the HW mode is determined according to the actual hardware.
boolean	Whether to check the CRC value of the data, optional
int	Mode, can only be onewire.GPIO or onewire.HW, optional

Return Value

return value type	explanation
number	Returns the temperature value on success, otherwise it returns nil. Unit 0.1 degrees Celsius

Examples

-- GPIO mode, connected GPIO 9
local temp = onewire.ds18b20(9, true, onewire.GPIO)
if temp then
    log.info("Read temperature value", temp)
else
    log.info("Read Failed")
end

---

onewire.dht1x(mode, pin, check)

Read DHT11

Parameters

Incoming Value Type	Explanation
int	GPIO The mode corresponds to the GPIO number, and the HW mode is determined according to the actual hardware.
boolean	Whether to check the CRC value of the data, optional
int	Mode, can only be onewire.GPIO or onewire.HW, optional

Return Value

return value type	explanation
number	Returns the temperature value on success, otherwise it returns nil. Unit 0.01 degrees Celsius
number	Returns relative humidity on success, otherwise returns nil. Unit 0.01%

Examples

-- GPIO mode, connected GPIO 9
local temp = onewire.dht1x(onewire.GPIO, 9, true)
if temp then
    log.info("Read temperature value", temp)
else
    log.info("Read Failed")
end
