Jeg vet ikke stort om hvordan man kan lage disse komponentene, men jeg klarer nok å sette de sammen. Jeg så et bilde av din esic_clone og den ser jo fin ut.
hvor har du montert disse temp følerene i huset ditt?
Hvilken funksjon har en DS18B20?

Tror du jeg kan bruke denne komponenten for å slå av/på aktuator? jeg ser bare at den bruker 433Mhz og ikke 433.96Mhz

Jeg laster opp en prinsipp skisse over hvordan jeg tenker dette skal fungere.

Hrrrm. Jag har inte monterat mina utan dom ligger provisoriskt utlagda utan låda och några av dom hänger i batterikabeln :)
Andra får svara på hur dom har gjort.

Du kan koppla tre olika typer av sensorer, varav en av dom kan du koppla in multipla av i en lång kedja. Notera att alla kan kopplas till samma esic_clone samtidigt.
1. DHT22 är en luftfuktighets sensor och en temperatursensor
2. DS18B20 är en 1-wire temperatursensor som ser ut som en liten transistor. Eftersom det är 1wire så kan du koppla in minst 10 stycken till varje esic_clone. Man kopplar dom som ett stjärnnät, en lång kedja eller något mix av båda. Seriekopplat är att föredra.
3. PIR-sensor är en rörelsesensor som ger en hög puls ut så fort den detekterar rörelse. Till den här ingången går det faktiskt att koppla vilken sak som helst som har digital signal ut. Så fort en signal går från låg till hög på den här ingången så sänder esic_clone ut ett paket.

När det gäller frekvensen så burkar i princip alla gå på 433,92MHz vilket förkortas 433MHz. Varför det inte oftast avrundas uppåt vet jag inte, men 433 är allra mest förekommande.
Jag vet inte om den komponenten du länkar till fungerar på Telldus produkter. Du kan nog nästan ta för givet att den inte fungerar om den inte är listad som kompatibel på deras hemsida.

Principskissen ser korrekt ut. Men notera att jag alltså inte vet om Wireless adaptiv switch fungerar. Det skulle ju vara coolt om den gjorde det.

ahh , takk for info om komponenter. da er jeg fortsatt usikker på hva esic clone gjør for noe. Jeg trodde det var en temp føler?
Jeg tror jeg skal bestille meg en slik wireless adaptive switch for å teste ut den sammens med en actuator. så da trenger jeg bare en tempføler jeg kan bruke.

Jeg tror jeg starter en ny tråd om styring av gulvvarme, så ser vi hvor vi til slutt ender :)
Det skal ikke mye til for å kunne lage et godt anlegg til en rimelig penge tror jeg.

Här är en principskiss över hur det är tänkt att fungera:

Esic_clone variants 2 - Google Drive.jpg
Esic_clone variants 2 - Google Drive.jpg (77.17 KiB) Viewed 9505 times
När det gäller DHT22 så kan man ha max en per esic_clone-enhet.
I exemplet ovan med DS18B20 så har jag testat med upp till 10 sensorer utan problem.


Hoppas detta gör det lite tydligare. Den starka sidan hos min sensor är att bara en enhet kan agera som multipla ESIC original-sensorer bara genom att addera ytterligare enskilda sensorkomponenter.
Och räckvidden förstås.

Edit: lagt till en bild och förtydligat.

Hi
It's a English board index it will be kind to write in english. thanks

Niclaf are you pcb design to your nice circuits ?

http://www.seeedstudio.com/depot/433mhz ... -1393.html should be a good project maybe you can open new ticket on telldus to update future new device ?

a question I ask myself what is product telldus use to BLOCKHEATER function on Events toolbox to control heater car ? It should be supply on 12VCC.

thanks

A blockheater is an electric heater inserted in the cooling water circuit of the car engine. It is connected to the 230V mains supply. We use it for pre-heating during winter. The blockheater function in Telldus calculates the time needed for heating as a function of outdoor temperature.

Calix and Defa are renowned manufacturers

Hi,

What kind of battery are you guys using for this and how long does it last? I want to try this little project!

Max voltage allowed is set by the pic, 5.5V. I have used both three and four AAA batteries. Note that if you use four batteries they need to be NiMh as they are 1.2V each.

Minimum voltage is limited by what sensors you have connected. You need to check the spec. The PIR need at least 4.5V. If you have one of those you need 4.5-5.5V

I will have esic_clone-kit ready for sale within a month I hope.

Edit: Changed dht22 to PIR

Checked it now. Here are respectively sensors voltage limits.

PIC12F675: min 3.0V - max 5.5V
DS18B20: min 3.0V - max 5.5V
DHT22: min 3.3V - max 6.0V
HC-SR501 (PIR): min 4.5V - max 14V

The PIC sets the maximum allowed voltage. It should never be higher than 5.5V.


Edit: Added PIC information.

Thanks for the quick reply! Was thinking of using "Coin batteries" at 3V first. How long does your setup with three or four AAA batteries last? Have ordered everything on eBay already except the batteries, so I'm playing the waiting game.

My guess is a year or more with 3 aaa. I have not had a device going without manipulating/updating/changing it.
A 3V cell will probably not last long. A lithium cell (3.6V) however would be fine an would likely last for a long time.

Edit: Added link and changed li-ion to lithium

How are things going with PCBs? Do you have any available for sale?

Great news! What will be the price for 4 inc. shipping (within Sweden)?
