HDC1000 NodeMCU module
|
||
|
|
=======================
|
||
|
|
|
||
|
|
Here's my NodeMCU module for the TI HDC1000 temperature and humidity sensor. It should work with the HDC1008 too but I haven't tested it.
|
||
|
|
|
||
|
|
### Setup your sensor:
|
||
|
|
First, require it:
|
||
|
|
|
||
|
|
`HDC1000 = require("HDC1000")`
|
||
|
|
|
||
|
|
Then, initialize it:
|
||
|
|
|
||
|
|
`HDC1000.init(sda, scl, drdyn)`
|
||
|
|
|
||
|
|
If you don't want to use the DRDYn pin, set it to false: a 20ms delay will be automatically set after each read request.
|
||
|
|
|
||
|
|
`HDC1000.init(sda, scl, false)`
|
||
|
|
|
||
|
|
Configure it:
|
||
|
|
|
||
|
|
`HDC1000.config()`
|
||
|
|
|
||
|
|
Default options set the address to 0x40 and enable both temperature and humidity readings at 14-bit resolution, with the integrated heater on. You can change them by initializing your sensor like this:
|
||
|
|
|
||
|
|
`HDC1000.config(address, resolution, heater);`
|
||
|
|
|
||
|
|
"resolution" can be set to 14 bits for both temperature and humidity (0x00 - default) 11 bits for temperature (0x40), 11 bits for humidity (0x01), 8 bits for humidity (0x20)
|
||
|
|
"heater" can be set to ON (0x20 - default) or OFF (0x00)
|
||
|
|
|
||
|
|
### Read some values
|
||
|
|
You can read temperature and humidity by using the following commands:
|
||
|
|
|
||
|
|
`temperature = HDC1000.getTemp()` in Celsius degrees.
|
||
|
|
|
||
|
|
`humidity = HDC1000.getHumi()` in %
|
||
|
|
|
||
|
|
### Check your battery
|
||
|
|
|
||
|
|
The following code returns true if the battery voltage is <2.8V, false otherwise.
|
||
|
|
|
||
|
|
`isDead = HDC1000.batteryDead();`
|
||
|
|
|
||
|

Happy making! Also, check out my Breakout Board and Arduino library for this chip: http://b.truzzi.me/hdc1000-temperature-and-humidity-sensor-breakout-with-arduino-library/.
