Remote monitoring EM01b Websensor re -engineered by Sequoia Technology for more robustness and lower cost

The EM01b used in server rooms and in IT circles for monitoring temperature , humidity and light levels over the internet has been re-engineered.

Following on from the success and popularity of the EM01b used in server rooms and in IT circles generally, for monitoring temperature , humidity and light levels over the internet, Sequoia has re -engineered the EM01b to be more robust and now selling at a much lower cost of £250. Sequoia is also about to re -introduce the ES01 display unit to be used on the ES bus of the EM01b. The ES01 has also been re -engineered to be smaller and much lower cost. This unit continuously displays the temperature, humidity and light levels that the EM01b is sensing and comes with a 3m cable. The ES01 is powered from the EM01b. We expect to be bundling the EM01b and ES01 very shortly with a considerable saving in cost.


The EM01b websensor comes alive when used with Nagios where alarm situations can be set up for email or SMS email messages to be sent automatically. The EM01b is a really useful remote monitoring tool and in use in many countries to date. This new generation should appeal to even more situations with its new low price and new accessories.
