## Description
|
|
|
|
|
|
|
|
|
|
The DHT22 is an often used sensor and many libraries are written for it
|
|
|
|
|
including my own https://github.com/RobTillaart/DHTNew library.
|
|
|
|
|
To better understand the protocol and to be able to debug my library
|
|
|
|
|
I wrote a simulator for the DHT sensors in 2014.
|
|
|
|
|
|
|
|
|
|
The simulator can be used to test applications to that use a DHT sensor,
|
|
|
|
|
e.g. to get high alarm temp or whatever.
|
|
|
|
|
|

|
|
|
Currently the code uses two analogue ports to get a value for temperature
|
|
|
|
|
and humidity. Just connect two potentiometers to play and simulate increase and
|
2021-01-29 12:31:58 +01:00
|
|
|
decrease of the temperature and humidity.

|
|
|
The simulator is not tested extensively so please report bugs.

- adjust the pins in the head of the program to meet your setup
|
|
|
|
|
- compile, connect, run

## Future
|
|
|
|
|
|
|
|
|
|
1) use the simulator-core as a bridge to other sensors.
|
|
|
|
|
Idea is to use the code of the simulator in combination with a
|
2021-12-16 17:29:43 +01:00
|
|
|
Sensirion or two separate sensors (DS18B20 + ? ) to provide an
|
2021-01-29 12:31:58 +01:00
|
|
|
accurate temperature and humidity. These could then be readable
|
|
|
|
|
with any DHT library with the performance of a DHT (~ 5ms).
|
|
|
|
|
(when time permits)
|
|
|
|
|
|
|
|
|
|
2) implement a recorder mode, to be able to replay a certain
|
2021-12-16 17:29:43 +01:00
|
|
|
behaviour time after time.
|
|
|
|
|
|
2023-10-24 15:56:14 +02:00
|
|
|
3) make a SHT Simulator class?
