Data Loggers


Onsite Weather Logger/Propeller
The OWL3pro is a data logger, capable of various and sundry tasks. It is based around the Parallax P8X32 Propeller, a 32 bit, 8 core microcontroller capable of running multiple routines in parallel. sensor, communication, and data processing.
More info

  • Supply Voltage: 5 to 24 VDC
  • Supply Current: less than 1mA
  • Gain accuracy: ±1%


OWL Data Logger
The OWL2pe is a data logger built around Parallax's BASIC Stamp. It includes digital and analog i/o, a battery backed real time clock, 512k memory, and many other powerful features. The OWL2pe can be used either on its own or as the core module to plug into a larger terminal board.
More info

  • uses the BASIC Stamp 2pe
  • 20 digital I/O
  • 9 analog channels with built in ADC
  • 512 Kbytes memory
  • I/O pin protection
  • provides 5-12VDC
  • additional 3.3 volts, 50mA, switched power

Counter Debouncer
The CT515 is a counter/debouncer chip that adds 5 counter input channels to the OWL2pe, Basic Stamp, Propeller, Arduino, or other microcontroller system.
More info
  • simultaneous and continuous debouncing and counting of all 5 inputs
  • 2.7V to 5V power supply
  • low power, 10 microamps while waiting for pulses
  • connection to microcontroller via a single pin with pullup resistor
