MULTIPLE UNIVERSAL ALARM ACTUATOR SOFTWARE WITH PHYSICAL HARD WIRED OUTPUTS THE SITE PROTECTION SYSTEM HAS GONE COMPLETELY HAYWIRE AND DOES NOT ALLOW POST EDITING ANY MORE AND NOBODY SEEMS TO CARE Please amend final part of previous post as follows: 8. Remember that to start the entire system the "...

MULTIPLE UNIVERSAL ALARM ACTUATOR SOFTWARE WITH PHYSICAL HARD WIRED OUTPUTS The following rules must be followed to implement the build procedure. 1. The click locations must be firmly fixed on the desktop screen. This result can be obtained as follows. - Right click on an empty spot on the desktop...

MULTIPLE UNIVERSAL ALARM ACTUATOR SOFTWARE WITH PHYSICAL HARD WIRED OUTPUTS Here is the FIGURE 1 which the system did not allow me to upload in the previous post, plus all the text files. Unfortuntely Arduino Files and AMC files have extensions which are not acceptable by the Picotech site, therefo...

MULTIPLE UNIVERSAL ALARM ACTUATOR SOFTWARE WITH PHYSICAL HARD WIRED OUTPUTS ALMSCRN3.jpg SIMPLE STEPS TO GET THE PC DESKTOP READY FOR OPERATION In the previous post we have seen how the Picolog Alarm condition is detected. The PC screen above shows how the PC desktop must look: in a word it must be...

MULTIPLE UNIVERSAL ALARM ACTUATOR SOFTWARE WITH PHYSICAL HARD WIRED OUTPUTS ALMSCRN1.jpg A major limitation of Picotech Data Loggers driven by Picolog is ( A ) the very limited number of hard wired outputs (for instance only 2 on the 1012 and 4 on the DrDAQ, to name a few) and ( B ) the absence of ...

MULTIPLE UNIVERSAL ALARM ACTUATOR SOFTWARE WITH PHYSICAL HARD WIRED OUTPUTS It is now possible to take any alarm generated by Picolog on any Picotech hardware type (both direct channel and calculated channel) and drive external devices (relays and/or microprocessors). The number of outputs can be a...

Ability to have the digital outputs (if available in the hardware) operated by the alarms of the Math Channels. At present only the input channel alarms operate the digital outputs. Work is being done to obtain independent, physical digital outputs for both physical and calculated parameter channel...

TEMPERATURE BEHAVIOUR AND AGING Air temperature into the sensor slightly influences the sensor's reading. Temperature correction can be applied according to the following table referred to an air temperature of +25°C: AIR TEMPERATURE °C......................CORRECTION -10..............................

ADDITIONAL TECHNICAL INFORMATION SPECIFICATIONS Two CO2 detectors based on the solid electrolyte technology are presently available: the MG-811 used for this series and the MG-812 which uses half the heating power. Specifications for both are given below. Note that the +12V input (Switching Regulat...

Sorry for the delay!

Yes, there is a complete CO2 measuring setup now, look at:

CO2 SENSOR OPERATION

Typical operation in outside open air, where typical CO2 concentration is 400 PPm +/- 10 PPM is illustrated in FIGURE 1. Sensor operation is quite stable.

A few recorded CO2 variations are shown in FIGURE 2.

SENSOR SIGNAL CONDITIONING & OTHER HARDWARE With reference to the MG-811 module schematic diagram, high input impedance / low drift U2A accepts the 1 GOhm output of U1 and amplifies the cell output voltage Vc by a factor of 8.5. With a cell output of 600 mV, the module output would be in excess of ...
