Re: Update:DIY wireless temperature sensor for Tellstick
Turned out that my pcb:s had a small fault
The LED is always on when it was supposed to only blink when sending data.
It is quite easy to fix. One cut of a trace and make a bridge.
You can get them cheap here, http://foogadgets.tictail.com

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 ha...

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. http://www.kjell.com/sortiment/el/batterier/litiumbatterier/batteri...

Re: Update:DIY wireless temperature sensor for Tellstick
Great that you build your own. I am actually learning to draw PCBs in Diptrace right now. I hope to have ordered a batch of pcb:s before the end of this week. The size of the pcb will be 24*24mm, including space for an optional 2.1mm power adaptor. Before mid of December I hope to be able to sell a ...

Interesting with the energy meter. At about mid of December I will have a kit ready for wirelessly send the energy readings from energy meters that have a blinking LED. It will be the same size as the esic clone. I hope to have a good enough solution for lost packages using a wireless protocol. I lo...

Re: Update:DIY wireless temperature sensor for Tellstick
Låter som ett spännande projekt. Min esic_clone skulle ju fungera perfekt i det här fallet.
Mitt förslag är att i så fall använda en esic_clone med 1 eller flera DS18B20 kopplade.

Re: Update:DIY wireless temperature sensor for Tellstick
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 ...

Re: Update:DIY wireless temperature sensor for Tellstick
I will sell them as a kit. 149:-+shipping(12:-) each including all components and a pre-programmed pic. There will be no sensor included since many want to buy the sender on its own to attach to their existing 1-wire network. I will however also sell the different sensors if you are interested. Ther...

Re: Update:DIY wireless temperature sensor for Tellstick
Här är en principskiss över hur det är tänkt att fungera: Esic_clone variants - Google Drive.jpg Esic_clone variants 2 - Google Drive.jpg 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 ...

Re: Rör termometer
Om man vill mäta 1-10 punkter så kan man ju använda min trådlösa multisensor som kan prata med 1-wire-sensorer av typen DS18B20 (-55C - 125C).
Den skickar ut det trådlöst så att Tellstick DUO/NET eller Rfxtrx433 förstår det. Räckvidden är stor.
