The LoRa Node measures barometric pressure, humidity, and temperature every 5 min. After the measurements, the ATtiny85 goes into sleep mode and is awakened by the watchdog timer. The RFM module sends the values to the TTN backend with Activation by Personalization (ABP) a fixed spreading factor and one of the four random channels.
The ATtiny85 based mini development board is similar to the Arduino, but cheaper and smaller (of course a bit less powerful)... With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE, this ATTINY85 USB Development Board is a great way to jump into microcontroller...

Back to all products 802272 - Atmel ATtiny85-20PU su Robot Italy Microcontrollore serie AVR, molto popolare perche' utilizzabile nel sistema Arduino. ATTINY85 Module. Digispark designed the original Tiny85 module, similar to the Arduino line, but cheaper. It caters for projects that need a low IO pin count. Quick Spec. Support for the Arduino IDE 1.0+ Power via USB or External Source - 5v or 7-35v (12v or less recommended) On-board 500ma 5V Regulator; Built-in USB [DaveAK] shares his latest (uncompleted, never really complete, are they) CAN Shield. Now I understand that there are a few CAN implementations out there, but the more the merrier, right? This one uses the MCP2515/MCP2551 chips like most of them do. It has a switchable CS pin so that you can use other SPI shields […] The device runs on 3 AA batteries in series. MCU is a attiny85 and transceiver is a 433 MHz HC-12. On the first run both devices will ping each other to confirm connection, after that the device goes in power-down-mode and is awoken by a interrupt when the mailbox is opened.
The H2OhNo! is a water sensor alarm kit that you build yourself. When water is detected across the sense pins an alarm goes off and an LED starts blinking. If you’ve ever had a water heater explode or tried to create submersible electronics you know how important it is to be able to detect when water is around!
The ATtiny85 can run on 2.7-5.5V without a regulator - so a 3.7V LiPo can power the board and make a cheap, effective, slim Arduino board. The best way to verify that the ATtiny Arduino is working properly is to upload a simple sketch. I supplied a simple blink sketch here to be used with pin 4 on the ATtiny.
