Low Cost Wireless temp/Humidity Logging

The TL Series is a wireless temperature and humidity logging system based on a USB based receiver base station and up to 50 remotely located transmitters. The TL series is suitable for a wide range of uses in both industrial and domestic applications. Over fifty wireless sensors can be installed and monitored by the USB base station and the included temperature logger software enables the monitoring and analysis of all the sensors separately.

The TL-300 is the entry level receiver whilst the TL-500 has stand alone data logging capability with 2Meg of built-in memory. There are several wireless sensors in the range covering indoor and outdoor temperature and humidity. The sensor range will be expended over time, with a CO2 sensor due out next. The sensors can be located up to 40m from the receiver and use the licence exempt 433Mhz radio band.

The easy to use Software presents the temperature measurements with time and date graphically. The Software keeps track of the data over several years and will log data (in the background) as long as your computer is running.

The logged measurements can be exported in several formats for further processing. The package includes a screensaver that dynamically displays the actual temperature for each sensor. An additional feature, when the software is installed, is Messenger software that enables temperature messages to be sent by email and to be published on a website. With an email-to-SMS service it is therefore possible to receive information from the temperature logger system on an SMS enabled device.

Available as starter kits which include either the TL-300 or TL-500 receiver, 2 wireless sensors, USB lead and software CD. Prices start from £56 ex VAT and delivery.

Multifunction USB DAQ Unit is Cheap but Fast

The U120816 is a very low cost USB data acquisition module which provides eight single-ended 12-bit analogue inputs, 16 digital I/O lines, two programmable pulse-width output channels, and one 16-bit counter channel. Analogue sampling rate is 32 ksamples/s maximum, with up to 13 ksamples/s for all 8 channels.

There are 8 single ended analogue input channels with an input range of 0-4.096V, 12 bit, so the resolution would be 1mv. The U120816 supports scan and streaming modes for data acquisition. The user can scan a single channel or scan multi-channels at once. In scan mode, the execution time is 8ms or 125Hz per channel. In streaming mode, the U120816 can start streaming data to the PC immediately or upon external trigger input, select through software. In trigger mode, a high state on the trigger line will start the data acquisition. The maximum throughput of streaming data varies with number of channels and they are also system dependant. Typically this is up to 32Ksamples/s for a single channel and 13Ksamples/s for all 8 channels.

There are 16 bi-directional digital I/O lines in U120816 module. Each line is software configurable to be either input or output high or output low. At power-up or reset, all lines are set to be input by default. All digital lines are 5V TTL and include a 470 ohm series resistor to provides over voltage/short-circuit protection. Each channel also has a 1M resistor connected to ground.

Thre is an external trigger line for streaming mode data acquisition. It is software configurable if the user wants to wait for this line. When in use, as soon as the line goes high, the device will start hardware timed data acquisition. This is a TTL level input.

There are two 10-bit PWM outputs in U120816. Software can set the period and duty cycle for each channel separately. The period is between 3 micro seconds to 333 micro seconds or the frequency is 333kHz to 3kHz. Duty cycle can be set between 0 – 100%. The PWM outputs can be used to light LEDs, drive motors, or convert to analogue outputs by adding an extra circuit.

The U120816 has a 16-bit counter. Software has the option to select if the counter should be reset after the read or not. The counter is incremented when it detects a falling edge followed by a rising edge. If you reset the counter while your signal is low, you will not get the first count until it goes high-low-high again.

The U120816 is supplied with the free application iDAQTest&Log. This package that can be used to test the U120816 device and log analogue input data and read back logged data for basic analysis. With this software, the user can browse through all the features in U120816, such as read single analogue channel, multiple analogue channels, streaming analogue input data continuously for display and log into file with or without external trigger, set DIO directions and read/write DIO states, set PWM output, read counter etc.

The U120816 also comes with a programming API iUSBDAQ.dll. This DLL can be called by third party applications. Programming examples are supplied in VB , ActiveX , dot net , C/C++ , Delphi, MacOSX. There is also a LabVIEW VI and program examples. Price for the U120816 is only £79
