SPT Series Transmitter
It’s based on the Texas MSP430 Ultra-Low Power MCU that also
includes a 10 Bit A/D Converter, Precision Voltage Reference
and Temperature Sensor.
The transmission protocol (D1 version) allows You to send
many interesting parameters and measures:
ID (24 bit), Analog Input (10 bit), Temperature (10 bit ),
4 Inputs On-Off status plus incremental transmission counter.
SPR Series Receiver
It’s based on the NXP LPC2103 ARM7 Microcontroller
loaded with a sophisticated program (D1 version)
to decode the 34 pulses string transmitted by the SPT
module with a self-adaptive AGC gain control system
to survive in the very difficult modern environments
with interferences and EMI broadband noise.
