I have run Slip21 new version now and replaced XBee with a remote temperature sensor. So The new Slip21 reports two
tempeatures. One is hooked under eave. The other is on the ground. (Dec28 2013)
I am interested in realtime web online measurement and writing my app titled Slip21. Slip21 gets ADC value of wireless
module XBee or MCU H8/3664 family, Tektronix DSO measurements through COM ports inculding USB to serial converters.
Slip21 records measured values and draws chart at real-time. Slip21 inquires the MCU and receives ADC outputs.
I adopted Akizuki's H8/3664F board and made a simple mother board with it. XBee has cyclic sleep mode for End Device.
The mode sends burst packets, when it gets up in a fixed period. The burst is sampled by short IO sampling period.
Slip21 always has to wait the burst. Slip21 edits the binary API packets and shows them by hex decimal expression.
Slip21 computes averaging ADC among 1-8 packets. The mother board of H8/3664 has a semiconductor temperature sensor,
a receiver of 2-wire remote temperature sensor and a load resistor of with two photo cells. If you have an old PC
running Windows XP later, Slip21 can run on it. My server's CPU is 400MHz with 384MB RAM. Slip21 needs Microsoft
.NET Framework 4 later. you can download at Microsoft site. Although Microsoft shows the minimun requirement,
the minimum requirement may be 1GHz-400MHz and 512-384MB in case of Slip21.
You see Slip.htm that Slip21 has listed the recent data H8/3664F or XBee got the two solar
cells output and the two temperature sensors and temperature sensor on XBee End Device. Press F5 key to update the
Measurements in case of IE browser, when MCU and Slip21 work now. The first number of the data means date and time. My
mother board works with my server all day now. It sometimes cannot update, when I rebuild the mother board.
I made two-wire remote temperature sensor circuit with 1.1 m shield cable. Refer to bundled 3664-1.pdf. M3 and M2
sensors are at 0.6m and 1.7m high on the same wall in vertical line. M4 is tempeature on floor. I moved the XBee End
Device on floor. So the temperature decended sharp. Looking at the chart, as for getting XBee ADC, It is necessary to
improve the sensing method including circuit to measure temperature correct. I know a bug to disappear the message on
the bottom of XBee Receiving Text Box, but I do not know the cause now. There is another known bug. It occurs, when
you save a parameter except for offset in the 'Setup' window. Select 'Continue' in the error message. I have fixed it.
I will publish the bug fixed version next time.
The chart shows the outputs of M2, M3 and M4. M2 is 2-wire remote temperature sensor on wall in Fig.1. M3 is
temperature sensor on mother board of MCU on wall. M4 is temperature on XBee End Device on floor.
Fig.2 shows Slip21 main form. Slip21 data format has recorded four Measurements more than a year. This version supports
to record XBee with conventional MCU/DSO at the same time. So Slip21 has to switch three ways for recording, MCU/DSO,
XBee and Both.
There are 8 recording cases for 1 to 4 Measurements as shown in Tbl.1
Tbl.1 Recording cases for Measurements
Fig.3 shows Slip21 get form. Slip21 integrated conventional TDS298 to get measurements this time. It is unnecessary for
Meas.txt to get ADC or measurements any more. The get form increased 'XBee' and 'Alarm' tab. Slip21 supports SSL mail
to send alarm, when ADC value exceeds Upper/Lower limiter.
