Sensor DHT11 with fezspider 2


#1

Hi, we are new in Gadgeteer.
Is it possible to use a DHT11 temperature and humidity sensor with fezspider 2?
We are using NETMF 4.3.
Someone can help us?
Thanks.


#2

yes.

start by using the search button in the upper right hand corner of this page

Hi Mike, I searched yet but I not find answers for NETMF 4.3


#4

I wanna know too


#5

Have you looked here? https://old.ghielectronics.com/community/codeshare/entry/228


#6

The problem is that he used PinCapture but in NETMF 4.3 there isn’t supported


#7

Check the documentation at old.ghielectronics.com for SignalCapture.


#8

I tried but i can’t find GHI.IO that contains SignalCapture


#9

check here code for NetFM 4.3/4.4 (i tested with netfm 4.3 and netfm 4.4 nucleo stm32f411ret6 and you need to use two pins from fez 2)

drivers / sample code and picture of connection

It is there? Where did you look?


#11

Thanks, i will try as soon as possible.

The DHT11 is a very poor sensor and not very accurate. It also has a poor life span too.

If you need something much better, have a look for the BME280 as this is I2C and easy to use and far more accurate. I use one for my home weather station.


#15

Show us your changes if possible :wink:


#16

I am interested in your solution too!

Looks like a school project, so who gets all the credits? :joy:

hoped he did better code than that i provided him…
but seems it was flagged with delete WITHDRAWN … :joy:
