A Serial 1-Wire
Recorder
This project builds on the success of it's
predecessor, TEMP05. LOG08 retains many of the previous features of the
TEMP05, and adds some extras.
Features of the LOG08 include;
-
Standard RS232 serial interface between the
Dallas/Maxim 1-Wire bus and a host PC
-
provides real-time relief for the host PC
by removing the burden of providing the precision timing required by the 1-Wire bus
-
No connection to PC required for
stand-alone logging
-
Polling display support for the following 1-Wire
environmental sensors;
-
DS18S20, DS18S20-PAR, DS1822, DS18B20 and DS1920
temperature sensors
-
DS2438 based Humidity Sensors
-
DS2423 based Lightning counters and
General Purpose counters
-
DS2423 based Rain Gauges
-
AAG 1-Weather Station (OWWS)
for wind speed, wind direction and outdoor temperature
-
Bray/Jennings DS2438 based Barometer
-
Dallas/Maxim iButtons (for security
applications)
-
Midon 1-Wire Relays (not yet
released)
-
Midon 1-Wire Humidity Sensor
MD3020E
-
Midon 1-Wire Voltage Sensors (not
yet released)
-
Midon 1-Wire LED Displays (not yet
released)
-
Logging support for the following 1-Wire
environmental sensors;
-
DS18S20, DS18S20-PAR, DS1822, DS18B20 and DS1920
temperature sensors
-
DS2438 based Sensors
-
DS2423 based counters
-
DS2450 based voltage sensors
-
Easy option programming (Set and Forget)
- NO option jumpers required.
-
Capability to interface up to 60
different sensors
-
On-board DS2438 temperature sensor
-
Optional on-board humidity sensor
-
On-board analog voltage input
-
Connectivity to 1-Wire bus via either
terminal strip or RJ-12 connector
-
Large EEPROM
capability for sensor logging
-
Discrete commands for
setting all important parameters
-
Real Time Clock for
displaying time of day with results of sensor polls
-
PCB Size fits into
optional PacTec CM5-125 case
-
EASY software upgrades
via recyclable processor changes
