You can also use a STX882. Vcc 1.2V - 6V

Hello,

I bought a few of the hc-sr501 sensors and am trying to use them. I have tried varying the potentiometers and the jumper and nothing changes - the output stays high.

I am applying +5v to the 3 pin connector correctly according to the schematics above.

Can someone suggest how I might get something to work ?

It does have a delay she it supposes to go to low… I believe 8 or 10 seconds without movement…
Did you try to wait sometime before measuring the output?

Hi all.

Here’s my Sender-Receiver Arduino. This is connected to a regular RasPi, so I left it out of the picture …

I used normal helical antennas for the process, but a straight wire might have been better. I wanted to use helical antennas for the looks (the devicebox is almost as small as the Arduino itself)
I made 2 of these, one for our summer home, one for my own home.

I have move the “topic” to show your mysensors…

@dynamite

i use the software YouScreen for capturing screenshots and upload them directly to my youscreen-account, i think its the easiest way…

Hello all,

My setup is still in an experimental stage.
I have a RasPi 2 (for now only running Pimatic) with a Homeduino and a MySensors gateway:

To the Homeduino some standaard wall switches and weatherstation sensors are connected.

The MySensors gateway is now used for some testing on self build sensors and actors.
The first sensor out of prototype phase to a more final solution is the battery PIR sensor based on a Arduino Mini Pro (modification: only led deactivated):

@Petjepet how you made the 433MHz antenna. Hiw long is the distance approx. for recieving signals? Which reciever are you using? Thanks

guess this should be the instruction for the antenna, right?

Right. The transmitter/receiver is the one recommended in the Homeduino section.

Hello all,
my new Aqua controller.

The main reason why I built:
Automatic exchange of water. (I’m tired of flying with buckets)
also able to:
4 channels to control lights
temperature measurement
controlled CO2
automatic feeder
and what someone invents
I would like to add:
pH and possibly EC

I used:
Wemos D1 R2
MOSFET Switch Module For Arduino
8 channel relay module
Prototype Screw Terminal Block Shield
2x DS18b20
3x level sensor
2x 12V water pump
1x 12V electrovalve

SW: ESPEasy
It’s all controlled from Pimatic over MQTT protocol.

Price: cca 35 EUR

Originally I had it on the Arduino Nano + Eth. But as it turned out, does not any similar software as ESPEasy for Arduino. And spend a few days writing software? I do not have enough time. And I certainly would not reach such quality.

That’s great!! I love it!!
If I would have had pimatic years ago as I still had my fishtank (450 liter) … ^^
Thx for sharing!

wow, really nice project
it was inspiring me for something like this…

Thank you very much. It’s just the beginning, I still need to fine-tune hardware and Pimatic.
When I finished, I will describe it in more detail.

@leader21 It is mounted in a box of malfunctioned DSL router.

Fishtank controller will continue with this:https://forum.pimatic.org/topic/2156/arduino-with-espeasy-as-a-i-o-expander

But I needed to also control the 230V outlet. It all costs around 20 Euros.
I’m glad you can not see the back side of perf board

Just a quick post of a project I have been tinkering with last few months. We moved to our current house about 2.5 years ago and still had a lot of work left in our garden. Finally this summer we had/made time to really give it a go. One of the things I did was dig a few trenches for an irrigation system:

I hooked it all up to my pump in the garage with Rainbird 24VAC valves:

I then started to work on a small controller board using an ESP8266 and a 4 channel relais board:

Then connected the controller to the pump and valves (1 switch for the pump and 24VAC transformer, 3 to the valves). The controller runs ESPEasy and is controlled via MQTT.

As this clearly is a testing rig, I still need to tidy up. Within a few days I am going to prepare the pump and valves for winter (don’t want the sprinklers and tubing to freeze obviously), which will be a good occasion to mount the electronics on the wall somewhere the next weeks. The keen eye can also spot a DHT22 temp/hum sensor, which will give me some information about the temperature near the pump and valves.

Off course I made a few switches in pimatic to turn things on and off, and made a few rules to switch off the pump in case I would forget.
Later on I made a few extra rules which are triggering the sprinklers at 6am in the morning based on the weather forecast. A week ago I received a soil moisture sensor, I still have to experiment with it but off course it will be used in the future to trigger the sprinklers based on the soil moisture content (and maybe weather forecast).

And a few more results after putting in a few rolls of grass. Still a lot of work to do, but already a huge improvement

i edited your post, since the dropbox pictures did not show up as expected.
nice project and thx a lot for sharing!!

@leader21 Thanks, I already was fiddling with the pictures and uploading them somewhere else, but then they magically appeared… so thanks mr Magic

Hi @Rene-Arts, very interesting project. It’s nice to see MQTT module to do something useful.

I have one question. The sensor is with ESP8266? From the picture it is not entirely certain. I’d included him on my list of devices with ESP. Thx and happy gardening.

@wutu If you are referring to the Greenthumb soil sensor; yup, its ESP8266 based. It is developed by a Dutch fellow I “know” from the Dutch Gathering-of-Tweakers forum (@koffienl spends a lot time there as well, as do a lot of other Dutchies over here). Thanks for your work on the MQTT plugins! I really like MQTT as it is so versatile and portable. Also it is supported by most home automation systems, which gives me some security of keeping stuff running in the future.
