They work for a few weeks and then the humidity sensor starts giving strange readings. Normally the temperature sensor is OK. I replaced the DHT22 with a SHT7x which is rated for outdoor use. My only worry is that I am using around 8 metres of ordinary 4-core telephone cable between the sensor and the Tx, but it appears to working OK. I embedded the SHT7x in a blob of Sugru inside an old Fine Offset transmitter.<br \/>\n<figure id=\"attachment_286\" aria-describedby=\"caption-attachment-286\" style=\"width: 278px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ejmilton.uk\/wp-content\/uploads\/2018\/09\/IMG_20180925_135747579-e1538144359191-278x300.jpg\" alt=\"SHT7x\" width=\"278\" height=\"300\" class=\"size-medium wp-image-286\" srcset=\"https:\/\/ejmilton.uk\/wp-content\/uploads\/2018\/09\/IMG_20180925_135747579-e1538144359191-278x300.jpg 278w, https:\/\/ejmilton.uk\/wp-content\/uploads\/2018\/09\/IMG_20180925_135747579-e1538144359191-768x830.jpg 768w, https:\/\/ejmilton.uk\/wp-content\/uploads\/2018\/09\/IMG_20180925_135747579-e1538144359191-947x1024.jpg 947w, https:\/\/ejmilton.uk\/wp-content\/uploads\/2018\/09\/IMG_20180925_135747579-e1538144359191-624x675.jpg 624w\" sizes=\"(max-width: 278px) 100vw, 278px\" \/><figcaption id=\"caption-attachment-286\" class=\"wp-caption-text\">External T\/H sensor<\/figcaption><\/figure><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Originally, I used a DHT22 as the external T\/H sensor but these devices don&#8217;t survive well outdoors.
