DHT11 Temperature/Humidity sensor

[mircogomiero]

Hi all
Iam starting to use this DHT11 sensor with PBP compiler and my Pic16f877.

I thought it was easier, but is not so.
I have to use port RC0 of PIC and change from output to input to enable the reading of DHT11
for mi is a big problem..
Does anyone have any idea?

This is a link for an example in mikroC compiler for ths DTH11 but I do not know how I can convert it in PBP

See DHT11 temperature sensor from china (http://www.protonbasic.co.uk/showthread.php/66835-DHT11-temperature-sensor-from-china?highlight=DHT11) at an other compiler site.

Hi,

While "pasting" existing projects ...

you could download the example programs Mikroelektronika gives in the SHT11 module apps ...

there's a Mikrobasic example you could translate much easier ... ;)

Hi Alain;

SHT11 is not the same as DHT11, they are much different!

Hi
yes SHT11 is I2C device (data/clock)
SHT11 have one wire serial comunication.
I still have not solved the problem, but this weekend we'll be working.
I'll keep you informed.

Many thanks

Sure protocols are quite different !!!

but handling comms with PBP "already cooked" functions is very similar, if you have a closer look at it ... :rolleyes:

just need a little effort ...
