I'll echo what Larry says > [@How to make a schematic you can post.](https://forum.arduino.cc/t/how-to-make-a-schematic-you-can-post/675103): > > When you submit a question on the forum you will usually need to add a schematic (circuit diagram). The tutorial that follows will explain some ways to create a useful image; however lets start by explaining how to add the image to your post. Its easy. Having created the image all you need to do is : Save the image somewhere convenient - maybe your desktop Start your post, and place the cursor (insertion point) where you want the image to be shown; [upload image to forum] 3: click th… and dont assume we keep data sheets in our heads, so please post links > **[DHT21 AM2301 Temperature & Humidity Sensor](https://hobbycomponents.com/sensors/840-dht21-am2301-temperature-humidity-sensor)** > > The DHT21 digital temperature sensor is one of the commonest from the range of DHT temperature sensors and boasts a relatively high temperature measurement accuracy of 0.5oC in 0.1oC steps with a relative humidity accuracy of +/- 3%.
