Questions & Answers about Vamos a controlar esos sensores.

Since we are learning the future tense, why does this sentence use vamos a controlar?
Vamos a followed by an infinitive is the informal future, used exactly like 'going to' in English. It is extremely common in spoken Spanish for near-future plans. If you wanted to use the simple future tense to say 'we will control', you would say controlaremos, which is a regular verb without an irregular stem.
I always mix up the words for 'those' and 'these'. How do I remember why we use esos here?
Esos means 'those' (further away), and estos means 'these' (close by). A helpful trick for Spanish learners is that 'this' and 'these' have T's (este, estos), but 'that' and 'those' do not (ese, esos).
Why is the plural of sensor spelled sensores instead of just adding an s?
Because the singular word sensor ends in a consonant. In Spanish, whenever a noun ends in a consonant, you make it plural by adding -es instead of just -s.
Is the a in vamos a controlar required, or can I just say vamos controlar?
The a is absolutely required! Whenever you use the verb ir (to go) to say you are going to do an action, you must always use the formula ir + a + an infinitive verb.
