Onsite Weather Logger

(OWL2pe)

52 pin module on 2" x 1.5" board, surface mount technology
- all parts rated -40 to +85 degrees Celsius industrial temperature range
- surface mount board manufactured in ISO 9002 facility
- fits in a standard enclosure, NEMA 4 weatherproof, 2" x 2.5" x 1.25"
- terminals "breakout" boards are available with Phoenix terminals.
- standard with 0.1" low profile header
BASIC Stamp 2pe-40 built in with all the latest commands
- see www.parallax.com
- or www.emesystems.com/BS2pe.htm
- 16 kbytes program memory on stamp
- plus additional 16 kbytes configuration data memory
20 digital multifunction I/O direct from Stamp available for user applications
- Stamp mainio, P0 to P15, all available.
- Stamp auxio X0 to X3
- On-OWL peripherals use auxio x4 to x15.
+9 channels of analog-to-digital conversion on external pins
- precision 0.05%, 4.096 volt reference.
- 12 bits, TLC2543, 1 millivolt per bit
+2 internal analog to digital channels
- monitor power supply voltage, Vin
- monitor on-board system temperature, -25 to +85 Celsius
I/O protected by 330 ohm resistors from miswiring and short circuit.
2RS232 system interface
- just like a standard BASIC Stamp, addressed as P16
- also used as programming port, just like any other BASIC Stamp.
- Built-in attention capacitor.
512kbytes (1/2 megabyte) of logging memory
- Atmel AT45DB041 dataflash for almost unlimited storage life
- 2048 pages of 264 bytes per page.
- holds memory without battery power.
- 50000 writes per page endurance.
- Accurate 1 second or 32khz heartbeat pulse is available to the BASIC Stamp for calibration or special purposes using the POLLWAIT commands.
Real time clock with memory
- DS1307 keeps accurate time from seconds to years
- lithium cell backup, included, keeps clock running for 10 years even when the main power is disconnected, automatic power switching.
- 56 bytes of battery backed RAM for system pointers and counters.
- On board temperature measurement can be used for software error correction.
- includes 528 bytes RAM memory buffer available to Stamp program
Power Supplies
- 5 volts constant at 200 ma, low dropout LT1521-5
- variable voltage (standard 5.5 volts, option 5 to 12 volts/200 ma) switched under program control LT1521
- 3.3 volts, 50 ma, switched under program control LT1761
- 4.096 volts reference (low current) switched under program control LT1790-4
- Low power consumption SLEEP modes, 50 microamps
- Operating current, 16 ma.
- 6 microamp standby option is available through external control of the main regulator.
