The IoT meter is equipped with a network interface. This makes the IoT meter an ideal solution for objects in which the measurement data must be continuously recorded and monitored. The IoT meter continuously stores the measured values \u200b\u200bon its internal memory. This is read out via browser or FTP client. The web browser also makes all the settings on the IoT meter. No additional software is needed. The architecture of the IoT meter allows up to 10 users to dial in to the IoT meter at the same time. Different access levels prevent unauthorized users from making settings to the IoT meter.<\/p>\n<p>In addition to storing the measured values, the IoT data logger for temperature and humidity can also alert the user to an alarm when the limit value is exceeded. Furthermore, various users can be notified of this alarm via email.<\/p>\n<p>The IoT data logger for temperature and humidity measures and calculates the following climatic variables:<\/p>\n<ul>\n<li>Temperature   <\/li>\n<li>Relative humidity<\/li>\n<\/ul>\n<ul>\n<li>Dew point<\/li>\n<\/ul>\n<ul>\n<li>Absolute humidity, ie amount of water vapor (in grams) per m\u00b3 of atmosphere at certain temperature<\/li>\n<\/ul>\n<ul>\n<li>Cooling limit temperature<\/li>\n<\/ul>\n<p>&#8211; Saturated vapor pressure, ie pressure, at which gas at the specified temperature in equilibrium with liquid (equilibrium between evaporation and condensation)<\/p>\n<ul>\n<li>Enthalpy (energy content)<\/li>\n<\/ul>\n<p>The IoT data logger for temperature and humidity is supplied via an external power supply unit or via Power over Ethernet. The built-in FTP server provides quick and easy access to archive files using an Internet browser or from the interface of another FTP client. The DHCP protocol allows you to automatically configure the datalogger on the computer network. Furthermore, the data logger supports the Modbus TCP \/ IP protocol, so that the PCE-HT 420 can also be integrated in machines. All these features make the PCE-HT 420 Datalogger an important instrument wherever indoor climate needs to be monitored.<\/p>\n<h3>Highlights<\/h3>\n<ul>\n<li>Temperature and humidity sensor<\/li>\n<li>Ethernet interface with MQTT function<\/li>\n<li>LCD display<\/li>\n<li>Alarms via email<\/li>\n<li>Audible warning sound<\/li>\n<li>8 GB memory<\/li>\n<\/ul>\n<h3>Technical specifications<\/h3>\n<ul>\n<li>Measuring range: humidity 0 &#8230; 95% rh (non-condensing)<\/li>\n<li>Accuracy: \u00b1 3% between 10 &#8230; 90%<\/li>\n<li>\u00b1 5% elsewhere<\/li>\n<li>Hysteresis\u00b1 1% RH<\/li>\n<li>Measuring range: temperature-20 &#8230; 60\u00b0C \/ -4 &#8230; 140\u00b0F<\/li>\n<li>Accuracy: \u00b1 0.6\u00b0C \/ 1.08\u00b0F in the range of 10 &#8230; 40\u00b0C \/ 10 &#8230; 104\u00b0F;\u00b1 1.0\u00b0C \/ 1.8\u00b0F elsewhere<\/li>\n<li>Dew point temperature \u00b0C \/ \u00b0F: Storage Internal ring buffer: 4 MB*<\/li>\n<li>Dew point temperature \u00b0C \/ \u00b0F: Internal hard disk 8 GB<\/li>\n<li>Dew point temperature \u00b0C \/ \u00b0F: *The measurement data from the internal memory is automatically transferred to the permanent memory<\/li>\n<li>Dew point temperature \u00b0C \/ \u00b0F \u2014 Interface: Ethernet 10\/100 Base \/ T<\/li>\n<li>Dew point temperature \u00b0C \/ \u00b0F: Number of connections Max. 10 at the same time<\/li>\n<li>MQTT \u2014 Power supply: DC power supply 6V \/ 1 A PoE IEEE 802.3af<\/li>\n<li>MQTT: Input&lt;2VA<\/li>\n<li>MQTT: Warm-up time 15 minutes<\/li>\n<li>MQTT \u2014 Operating conditions: -20 &#8230; 60\u00b0C \/ 95% rh<\/li>\n<li>MQTT: Degree of protection IP20<\/li>\n<li>Assembly Rear mounting hole for wall mounting \u2014 Sensor: downwards<\/li>\n<li>Assembly Rear mounting hole for wall mounting \u2014 Weight: 300 g \/ &lt; 1 lb<\/li>\n<li>Assembly Rear mounting hole for wall mounting \u2014 Dimensions: 120 x 80 x 25 mm \/ 4.7 x 3.1 x 1 in<\/li>\n<\/ul>\n<h3>Delivery scope<\/h3>\n<ul>\n<li>1 x IoT Data Logger PCE-HT 420IoT<\/li>\n<li>1 x User manual Note: The power supply must be selected as an option!<\/li>\n<\/ul>\n<h3>Documents<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.pce-instruments.com\/eu\/api\/getartfile?_fnr=1767322&amp;_dsp=inline\">Supplier document<\/a><\/li>\n<li><a href=\"https:\/\/www.pce-instruments.com\/eu\/api\/getartfile?_fnr=1767325&amp;_dsp=inline\">Supplier document<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>IoT Data Logger for Temperature and Humidity PCE-HT 420 Data logger for temperature and humidity \/ MQTT \/ Power supply unit or PoE (Power over Ethernet) \/ LC display \/ Visualization in web browser \/ 8 GB memory.
