What is a Tmote ?
 Reliable low-power wireless sensor. Moteiv
http://www.moteiv.com/
 Moteiv is a venture-funded company that
provides wireless sensor networking solutions
to enterprises worldwide.
 Moteiv's founding team has several decades of
collective experience leading the
implementation of the world's largest wireless
sensor network deployments from UC
Berkeley.
Different motes for different

Different Tmotes
 Tmote Sky
 Widely proven platform for wireless sensor systems
deployments.
Tmote Sky is the wireless sensor module of choice
for large-scale, high data-rate sensor network
applications requiring ultra low-power, high-reliability
and ease of development.
 Tmote Sky offers a number of integrated peripherals
including a 12-bit ADC and DAC, Timer, I2C, SPI,
and UART bus protocols, and a performance
boosting DMA controller.
Different Tmotes

Tmote Invent




Wireless sensing unit.
Pre-integrated on-board sensors.
Light, temperature, vibration (2-axis
accelerometer) and sound (microphone).
Tmote Invent includes a speaker for
auditory feedback, headphone jack for
discrete applications, and LEDs for visual
feedback.

Trawler Application:
TinyOS
 TinyOS system, libraries, and
applications are written in nesC.
 nesC applications are built out of :
 Components with well-defined, bidirectional
interfaces.
 nesC concurrency model:
 tasks and hardware event handlers
 detects data races at compile time.
Blink Application:
 Blink.nc configuration Blink {
}
implementation {
components Main, BlinkM, SingleTimer,
LedsC;
Main.StdControl -> BlinkM.StdControl;
Main.StdControl -> SingleTimer.StdControl;
BlinkM.Timer -> SingleTimer.Timer;
BlinkM.Leds -> LedsC;
}
Blink Application:
 BlinkM.nc module BlinkM {
provides {
interface StdControl;
}
uses {
interface Timer;
interface Leds;
}
}
Blink Application:

implementation {
command result_t StdControl.init() {
call Leds.init();
return SUCCESS;
}
command result_t StdControl.start() {
return call Timer.start(TIMER_REPEAT, 1000) ;
}
command result_t StdControl.stop() {
return call Timer.stop();
}
event result_t Timer.fired()
{
call Leds.redToggle();
return SUCCESS;
}
}
nesC Documentation:
Component: Blink2
configuration Blink2
Blink2 is a basic application that toggles the
LEDs on the mote on every clock interrupt. The
clock interrupt is scheduled to occur every
second. The initialization of the clock can be
seen in the Blink2 initialization function,
StdControl.start().
